TG Bot Customer Service Not Responding? Complete Troubleshooting Guide from Agent to User

Setting up a Telegram Bot customer service system, the most frustrating scenario is: users send messages with no response, and agents don’t receive any notifications. This “TG bot customer service not responding” issue can be caused by any glitch in network, configuration, permissions, or rules.

This article provides a complete set of troubleshooting steps from the underlying network to the upper business logic. Whether you use TG-Staff or another Bot management platform, this approach can help you quickly pinpoint the cause and resume normal service.

Why is TG Bot Customer Service Not Responding? First, Identify the Problem Level

When encountering a Bot that doesn’t respond, don’t rush to suspect system failure. First, ask three questions:

• User side: After the user sends a message, does the Bot show “Online”? Does the user receive an automatic reply (e.g., welcome message)?
• Agent side: Can the agent see the new conversation in the web console? Have they tried to reply but the message wasn’t delivered?
• System side: Is the Bot Token valid? Has the plan expired? Is the Webhook working?

Categorizing the problem into these three levels will give you direction for subsequent troubleshooting. Follow the steps below to verify one by one.

Step 1: Check Basic Network and Telegram API Connectivity

Network issues are the most common cause of TG bot customer service not responding. The Telegram Bot API relies on a stable internet connection. If your server or local network cannot access api.telegram.org, the Bot naturally cannot send or receive messages.

Quick verification methods:

1. Use a browser or command line to visit https://api.telegram.org/bot<你的Token>/getMe
   • If the returned JSON contains the Bot’s ID and name, the API connection is normal.
   • If it times out or returns an error, the network is blocked or DNS resolution fails.
2. Check the Bot’s status in the Telegram client: Open the Bot’s chat page. If it shows “Online” or “Recently Seen”, the Bot Token is valid and can receive messages.
3. If using TG-Staff, go to Console → Project Management → the corresponding Bot’s “Webhook Status” to see if it shows “Normal”.

Common network fault handling:

• Server IP blocked by Telegram (change IP or use a proxy).
• Local development environment cannot directly connect to Telegram API (need to configure a proxy or use an overseas server).
• Firewall rules mistakenly block Telegram’s IP ranges.

Step 2: Confirm Bot Token and Webhook Configuration Are Correct

Incorrect Token or invalid Webhook is the second most common cause of TG bot customer service not responding.

Verify Token:

1. Open @BotFather in Telegram, send /mybots, select your Bot, and click “API Token”.
2. Copy the Token and compare it with the one in TG-Staff Console → Project Management → Bot Token field. If they don’t match, update with the correct Token.
3. If the Token has been reset (e.g., you clicked “Revoke token” in BotFather), the old Token becomes invalid immediately.

Check Webhook:

• In TG-Staff Console → Project Management → the corresponding Bot’s “Webhook Settings”, click “Check Status”.
• If it shows “Not Set” or “Error”, click “Set Webhook” to rebuild.
• You can also manually verify: visit https://api.telegram.org/bot<你的Token>/getWebhookInfo and confirm that the url field points to TG-Staff’s Webhook URL.

Step 3: Troubleshoot the Agent Side — Why Can’t Agents See User Messages?

Sometimes the Bot can receive messages normally, but agents cannot see new conversations in the Web console. The problem often lies on the agent side.

Agent Not Logged In or Session Expired

TG-Staff’s Web console sessions have a validity period. If an agent has been inactive for a long time, their login status may expire.

Solution: Refresh the page. If redirected to the login page, log in again. It is recommended that agents confirm they are logged in before starting work.

Agent Does Not Have Customer Service Permissions for the Project

If the project is configured with “designated agents”, agents not on the list cannot receive messages from that Bot.

Check steps:

1. Go to TG-Staff console → Project Management → Select the corresponding Bot.
2. Find “Customer Service Scope” and confirm whether the current agent is in the “Designated Agents” list.
3. If the project is set to “All Agents”, all agents can receive messages; if only some agents are selected, other agents cannot see the messages even if they are online.

Step 4: Check if Session Routing Rules Cause Message Loss

TG-Staff supports two routing rules: Round Robin (default) and Online First. If the rules are set improperly, messages may be assigned to offline agents, causing users to wait.

Comparison of the two rules:

Rule	Behavior	Suitable Scenario
Round Robin	Polls all authorized agents in order, regardless of online status	Teams with many agents and shift-based work
Online First	Prioritizes online agents; falls back to round robin when all are offline	Small teams or agents always online

Troubleshooting method:

1. In TG-Staff console → Project Management → Routing Rules, check the current setting.
2. If “Round Robin” is selected, check if any agents are offline. When an offline agent is polled, the message enters a queue but is not immediately assigned.
3. If all agents are offline, messages enter a waiting queue. The user will not receive a reply until an agent comes online and manually picks up the message.

Step 5: Troubleshoot Bot Command Flow and Auto-Reply Settings

If a user’s message triggers the Bot’s automatic command flow (e.g., welcome message, menu) but doesn’t correctly route to a human agent, it can also result in the tg bot customer service not replying.

Checklist:

• In the TG-Staff console → Visual Command Flow, open the current Bot’s flow editor.
• Confirm that after the auto-reply node, there is a “Transfer to Human” node connected.
• Common mistake: After the user sends a keyword, the Bot only replies with an automated message but doesn’t trigger session assignment. You need to add a “Transfer to Human” node in the flow and set it as the endpoint.

Testing Method: Simulate a user sending a message with another Telegram account and observe whether the flow executes as expected. If auto-reply works but no human session is created, the flow is missing the transfer-to-human step.

Step 6: Check Content Moderation and Message Blocking (Pro Version)

If you are using the TG-Staff Pro version, content moderation rules may have blocked messages sent by agents, causing users not to receive replies.

How to View Content Moderation Trigger Logs

1. Go to TG-Staff Console → Content Moderation → Trigger Logs.
2. Filter by time range, agent, or risk phrase.
3. View the blocked message content and trigger time. If an agent’s reply was blocked, detailed records will appear here.

Is Wallet Address Monitoring Causing False Positives?

Many Web3 and cryptocurrency teams configure wallet address keywords (e.g., TRC20/ERC20 address fragments) in content moderation to prevent agents from mistakenly sending payment addresses. However, such rules can falsely block normal replies—for example, if an agent replies with “Transaction hash: xxxx” and the hash contains a configured address fragment, the message will be blocked.

Solutions:

• Set wallet addresses to “exact match” rather than “fuzzy match” in risk phrases.
• Regularly review trigger logs and add false-positive strings to a whitelist (if supported).
• If this feature is not needed, temporarily disable risk phrases or lower the blocking level.

Step 7: Check Whether Auto-Translation Causes Message Send Failures

TG-Staff’s auto-translation feature relies on third-party APIs (e.g., DeepL, Google Translate). If the API quota is exhausted or the network is abnormal, translation failure may prevent messages from being sent.

How to Check:

1. In TG-Staff Console → Settings → Translation, view the translation quota usage of the current plan.
2. If the quota is exhausted, the translation feature will automatically stop. Messages sent by agents will fail, and users won’t receive replies.
3. If the quota is sufficient but translation still fails, check the console for translation error logs (if available).

Temporary Workaround: Disable auto-translation and have agents manually reply in the original language. Re-enable after quota is restored or the network stabilizes.

Frequently Asked Questions

Q: The tg bot customer service is not replying, but the Bot shows “Online” on the user’s end. What should I do?

A: The Bot showing “Online” only indicates that the Bot Token is valid and can receive messages. It does not mean an agent is logged in or a session has been assigned. Follow the steps above to check agent status, routing rules, and project permissions. If all agents are offline, user messages will enter a queue but won’t receive replies.

Q: Why can agents see user messages, but users cannot receive agent replies?

A: This is usually caused by: 1) Messages sent by agents are blocked by content moderation rules (Pro version); 2) Auto-translation API call fails, preventing message delivery; 3) The user has blocked the Bot (need to guide the user to unblock). It is recommended to first check content moderation trigger logs and translation quotas.

Q: The same Bot worked fine before but suddenly stopped replying. What could be the reason?

A: Common reasons include: 1) The Webhook was accidentally modified (e.g., by resetting the Token via BotFather); 2) TG-Staff subscription expired or trial ended, causing service suspension; 3) Temporary Telegram API failure (rare). It is recommended to first check the console “My Subscription” status, then verify the Webhook.

Q: When using TG-Staff, what happens if the number of agents exceeds the plan limit?

A: If the number of agents assigned to a current project exceeds the plan’s supported agent limit (e.g., Standard Edition supports 3 agents), newly added agents will not be able to receive new messages, while existing agents remain unaffected. It is recommended to check the current plan’s agent limit in the console “My Subscription” and reasonably allocate customer service scope.

Q: Is the tg bot customer service not replying related to the user’s Telegram client version?

A: The possibility is extremely low. The Telegram Bot API is a server-side standard interface and has nothing to do with the user’s client version. If users can send messages normally and see the Bot’s “Online” status, the problem almost always lies in server-side configuration, not the client.
