Telegram Bot Troubleshooting FAQ Hub: Webhook, Connection, and Customer Service Common Issues Complete Guide

Running a Telegram Bot customer service system, the biggest fear is not a high volume of user inquiries, but the Bot suddenly “going on strike”—messages not being sent, Webhook errors, or agents not receiving conversations. These issues not only affect user experience but can also lead to potential customer loss.

As a customer service and operations SaaS platform for Telegram Bots, TG-Staff not only helps teams efficiently manage customer service but also accumulates extensive troubleshooting experience. This article compiles the high-frequency issues you encounter—from Bot connection anomalies and Webhook configuration errors to TG-Staff agent assignment and content moderation blocking—into a bookmarkable FAQ hub. Whether you are just registering for a trial or have been using it deeply, you can find a quick fix path here.

Common Telegram Bot Connection and Response Troubleshooting

The Bot failing to reply to user messages is the most destructive fault in operations. The problem may lie in the Bot’s own configuration, server network, or third-party platform connections. Below are troubleshooting steps in order of priority.

What to do if the Bot suddenly stops replying to user messages?

When encountering this situation, don’t rush to restart the server. Check the following four steps in order:

1. Check if the Bot Token is valid
   Open Telegram, send /mybots to @BotFather, select your Bot, and click “API Token”. If the Token shows as reset or abnormal, regenerate it and update it in your code or TG-Staff.

2. Verify Webhook status
   Visit the following address in your browser (replace <你的Token> with the actual value):
   https://api.telegram.org/bot<你的Token>/getWebhookInfo
   In the returned JSON, pay attention to whether the url field points to your server address, as well as the last_error_date and last_error_message fields. Common errors include "SSL certificate error" or "Connection timed out".

3. Confirm the server IP is not blocked by Telegram
   Telegram’s API servers dynamically block certain IP ranges. If the server is in a data center or cloud service provider, try changing the IP or check if the firewall allows Telegram’s IP ranges (Official IP List).

4. Check if the SSL certificate is valid
   The Webhook URL must be HTTPS, and the certificate must be issued by a trusted CA. Self-signed or expired certificates will cause Telegram to reject the connection.

How to Handle “Bad Request: can’t parse entities” After Webhook Setup?

This error usually occurs when the bot sends a message containing format symbols that Telegram cannot parse (such as _, *, [, etc.). In TG-Staff, if an agent sends a message with Markdown or HTML tags that are incorrectly formatted, this error will be triggered.

Solutions:

• Disable message format parsing: In TG-Staff’s message sending settings, change the parse mode to “None” or “Plain Text”.
• Escape special characters: If formatting is necessary, ensure that characters like _, *, ~ have a backslash \ added before them for escaping.
• Check auto-translation feature: If auto-translation is enabled, text in certain languages (e.g., Russian, Arabic) may contain Unicode characters incompatible with Telegram, causing parsing failures. Temporarily disable translation for testing.

Typical Failures and Fixes in TG-Staff Customer Service System

TG-Staff forwards bot messages to a web console, where agents reply. The following two issues are most common for new teams.

Agent Sees No Conversations or User Messages After Login

This is usually a permission configuration issue, not a system fault. Follow these steps to troubleshoot:

1. Confirm the agent has been added to the project
   Log in to the TG-Staff console → Go to “Project Settings” → “Agent Management”. Check if the agent appears in the “Project Agents” list. If not, click “Add Agent” and enter the agent’s TG-Staff account email.

2. Check agent role and permissions
   In “Team Management”, ensure the agent’s role has permissions for “View Conversations” and “Reply Messages”. If the role lacks permissions, create a new role with full agent permissions and assign it.

3. Verify conversation routing rules
   If the project has enabled “Conversation Routing” and the rule is set to “Specific Agents”, only selected agents can see new conversations. Go to “Project Settings” → “Conversation Routing” and check if the current rule is “All Agents” or includes the agent.

Bot Not Auto-Replying After Diversion Link (Magic Link) Redirect

Diversion Links are a feature available in TG-Staff Standard and above plans, used for ad attribution. If a user clicks the link and is redirected to the Bot but doesn’t receive a welcome message, possible reasons include:

• Link expired: Each diversion link is valid for 30 days. After expiration, you need to generate a new one.
• Bot not configured with a welcome flow: In TG-Staff’s “Visual Command Flow”, you need to set up a “New User Welcome Message” or “/start command response” for the Bot. Without this, users will only see a blank dialog after redirection.
• User has blocked the Bot: If the user previously blocked the Bot, clicking the diversion link won’t trigger any reply. Advise the user to unblock the Bot first.

Best Practice: Before launching an ad link, run through the entire process with a test account—click the link → redirect to Telegram → receive welcome message → trigger human agent. Ensure each step works correctly.

Troubleshooting Session Routing and Agent Assignment Issues

Session routing is a core feature for improving customer service efficiency, but improper configuration can lead to agents not receiving new sessions or being assigned repeatedly.

Round-Robin vs. Online-First: How to Choose?

TG-Staff offers two routing modes:

Routing Mode	How It Works	Use Case
Round-Robin	Polls all agents with permissions in order, regardless of their online/offline status	Shift-based customer service, requiring fair workload distribution
Online-First	Prioritizes agents currently online; falls back to round-robin when all are offline	Teams distributed across time zones needing real-time response

Common Issue: If an agent is online but not receiving new sessions, check:

• Is the routing mode set to “Online-First”? If so, the agent must be in “Online” status (green indicator in the top-right corner of the console).
• Is the agent currently handling other sessions? TG-Staff allows agents to handle multiple sessions simultaneously, but if the agent manually sets their status to “Busy”, the system will stop assigning new sessions.
• Does the project’s agent scope include this agent? Go to “Project Settings” → “Session Routing” → “Agent Scope” and confirm the agent is checked.

Agent Not Receiving New Session Notifications

If an agent hasn’t enabled browser notifications or hasn’t kept the TG-Staff console page open, they may miss new session alerts. Suggestions:

• Allow TG-Staff desktop notification permissions in the browser.
• Agents can enable Telegram Bot notifications (bind notifications via @tgstaff_robot).
• If the team uses mobile devices, advise agents to install Telegram on their phones and follow the Bot’s real-time messages.

Handling Message Send Failures and Content Moderation Triggers

When agents fail to send messages, the cause may be quota limits, network issues, or content moderation rules.

Auto-Translation Quota Exceeded

TG-Staff Standard and Pro plans both offer auto-translation, but with daily quotas based on the plan. If an agent sees a “Translation quota exhausted” prompt after sending a message, you can:

• Go to the console “My Subscription” to check current plan translation usage.
• Temporarily disable auto-translation and switch to manual translation or other tools.
• Upgrade the plan (e.g., from Standard to Pro) for a higher quota.

False Positive in Content Moderation

The Content Moderation feature (Internal Control) in the Pro plan checks for risk words before agents send messages. If a normal message is blocked, the risk word configuration may be too strict.

Troubleshooting Steps:

1. Log in to TG-Staff console → “Project Settings” → “Content Moderation”.
2. View “Trigger Records”, find the blocked message, and see which specific risk word was hit.
3. If it’s a false positive, you can:
   • Temporarily remove the risk word.
   • Group risk words and adjust the trigger threshold (e.g., set to “Popup Confirmation” instead of “Direct Block”).
   • Exclude specific agents or session types from the risk word group.

Note: Content Moderation is particularly useful for Web3, exchanges, etc., to monitor whether agents mistakenly or improperly send cryptocurrency wallet addresses (e.g., TRC20/ERC20 addresses). Ensure the risk word list is accurate to avoid affecting normal customer service communication.

Payment and Subscription Management Issues

Financial-related issues, though infrequent, can directly impact Bot functionality. Below are common problem resolutions.

Payment Made but Plan Not Effective Immediately

After paying via Stripe or USDT, TG-Staff typically syncs the plan status within 1–5 minutes. If it hasn’t taken effect after 10 minutes:

• Check if the payment was successful: For Stripe, check bank deduction records; for USDT, check on-chain transaction confirmations (recommend waiting for 6 confirmations).
• Re-login to the console and go to “My Subscription” to check plan status.
• If the status still shows “Free Trial” or “Expired”, contact @tgstaff_robot customer service Bot with payment proof (Stripe receipt number or transaction hash) for manual refresh.

Bot Functionality Limited After Subscription Expiry

After subscription expiry, TG-Staff stops Webhook forwarding, and the Bot cannot receive or reply to new messages. Upon renewal, the system automatically restores functionality. If it doesn’t, follow the steps above to contact support.

Failure to Change Subscription Cycle

In the console “My Subscription”, click “Change Plan”, select a new cycle (e.g., from 30 days to 90 days) and payment method. If an error popup appears, it’s usually due to a Stripe subscription conflict. Solutions:

• Cancel the current subscription first (via Stripe Billing Portal or contacting support), then resubscribe.
• If paying with USDT, ensure the on-chain transfer amount matches the target plan price exactly (including network fees).

Frequently Asked Questions (FAQ)

Q: Telegram Bot Webhook keeps reporting errors after setup. How to troubleshoot?

A: First confirm the Bot Token is correct, then visit https://api.telegram.org/bot<你的Token>/getWebhookInfo in your browser to check the Webhook URL and error message. Common causes include URL not being HTTPS, invalid SSL certificate, or server IP blocked by Telegram. If the error message contains "can't parse entities", check for formatting symbols in the message text.

Q: When using TG-Staff, an agent is online but not receiving new sessions. Why?

A: Check if the session routing rule is set to “Online-First” mode, and confirm the agent is added to the current project’s “Agent Scope”. Also, check if the agent is in “Busy” status (handling another session) or if browser notifications are muted.

Q: After clicking a diversion link (magic link), the Bot doesn’t auto-reply. What’s the issue?

A: First confirm the Bot is properly connected to TG-Staff and has a welcome message or command flow configured. Next, check if the diversion link has expired (valid for 30 days) or if the user has blocked the Bot. It’s recommended to run a full test with a test account before launching ads.

Q: An agent’s message was blocked by content moderation. How to resolve?

A: Log in to TG-Staff console and go to “Project Settings → Content Moderation” to view trigger records. If it’s a false positive, temporarily remove the triggering keyword or adjust the risk word group; if it’s intentional, advise the agent to modify and resend the message. Note that moderation rules can be configured independently per project.

Q: Bot functionality is limited after subscription expiry. How long until it’s restored after renewal?

A: After payment via Stripe or USDT, the system typically syncs the plan status within 1–5 minutes. If it hasn’t restored after 10 minutes, contact @tgstaff_robot customer service Bot for manual refresh. It’s recommended to renew 3 days before expiry to avoid service interruption.
