Telegram Customer Service AI Translation Not Working? 7 Common Causes and Troubleshooting Steps (TG-Staff User Guide)

When cross-border customer service teams handle multilingual messages daily, AI translation is an indispensable efficiency tool. However, many TG-Staff users report that AI translation suddenly stops working—English messages from others are not automatically translated into Chinese, or translated messages are not sent out.

In such cases, 90% are not system failures but due to configuration details, quota limits, or usage habits. This article provides a standard troubleshooting process covering the 7 most common causes, from quota checks to risk control blocks, helping you quickly restore translation functionality.

Troubleshooting Step 1: Check if the Plan and Translation Quota Are Exhausted

AI translation relies on daily quotas. The quotas differ between the Standard and Pro plans. If the daily quota is used up, the translation toggle remains on but translation will not actually be performed.

How to Check Remaining Quota?

Log in to the TG-Staff Console → Left menu “My Subscription” to see your current plan, expiration date, and today’s used/total quota.

Plan Type	Translation Quota
Free Trial	Standard plan quota (see console prompt for details)
Standard	Daily limit (approximately hundreds per day)
Pro	Unlimited translation

Behavior When Quota Is Exhausted

• The translation toggle still shows as enabled
• Messages are no longer automatically translated
• You need to wait for reset at UTC 0:00 the next day, or upgrade to Pro (unlimited translation) to unlock immediately

Troubleshooting Step 2: Check Translation Toggle and Auto-Translation Settings

Sufficient quota but translation not working? Next, confirm that the translation toggle is actually enabled.

Project-Level vs. Session-Level Translation Settings

TG-Staff’s translation configuration has two levels:

• Project-Level: Configure default source and target languages in project settings (e.g., Auto-detect → Chinese). All new sessions inherit this setting by default.
• Session-Level: Each session window has an independent translation toggle in the top-right corner, allowing you to temporarily modify the language pair.

Common mistake: Project-level translation is enabled, but a specific session window has manually turned off the translation toggle. Check each active session to ensure the translation icon is lit up.

Common Configuration Oversights: Not Saved or Not Applied to Agents

After modifying translation settings, be sure to click the “Save” button at the bottom of the page. If the agent side hasn’t received updates, try:

1. Refresh the web agent page (F5 or Ctrl+R)
2. Log out and log back in
3. Clear browser cache (especially after translation configuration changes)

Troubleshooting Step 3: Confirm Message Language Matches Target Language

The AI translation source language defaults to “Auto-detect.” However, auto-detection is not 100% accurate—when users send messages containing mixed languages, abbreviations, typos, or special characters, the AI may misidentify the language, leading to:

• No translation response (detected source language same as target language)
• Garbled output or no translation at all

Manually Specify Source Language

In the session window’s translation settings, change the source language from “Auto-detect” to the actual language of the message (e.g., English → Chinese). This significantly reduces recognition errors.

Best Practice: If your team primarily handles specific language pairs (e.g., Chinese → English, Japanese → Chinese), it’s recommended to specify them directly in the project-level settings rather than relying on auto-detection.

Troubleshooting Step 4: Check Network and Telegram API Status

AI translation depends on the TG-Staff server and external translation APIs (e.g., OpenAI, Google, or DeepL). The following situations can cause translation timeouts or failures:

• Unstable network connection (especially WebSocket disconnection)
• Telegram Bot rate-limited (sending too many messages in a short time)
• Temporary TG-Staff server anomalies

Quick Diagnostic Methods

1. Refresh the web agent page and check if the connection status in the bottom-left corner is green
2. Send a regular message without translation to confirm it reaches the user normally
3. Check if the Telegram Bot is online (send /start to the Bot in Telegram and see if it responds)
4. Try restarting the Bot: In BotFather, you don’t need to redeploy; simply disconnect and reconnect TG-Staff’s WebSocket (Console → Project Settings → Reconnect)

Troubleshooting Step 5: Is Content Moderation (Internal Control) Blocking Translated Messages?

This is the most commonly overlooked troubleshooting point for professional users. The Content Moderation feature detects risky words before an agent sends a message. If the translated message triggers a risk phrase, it may be blocked from being sent—meaning you see the translation result, but the user doesn’t receive it.

Solution

• Add commonly used foreign words (e.g., “payment”, “wallet”) as whitelist entries in the risk phrase list
• Change the interception mode from “Block sending” to “Double confirmation” so agents can manually confirm before sending
• If risk control is not needed, temporarily disable the corresponding phrase

Troubleshooting Step 6: Translation Delay and Cache in Multilingual User Scenarios

When multiple messages are sent rapidly in a conversation, AI translation may experience a brief delay (typically 1–3 seconds). Additionally, the browser may cache previous translation results, causing new message translations not to display in time.

Recommended Actions

1. Wait 3–5 seconds after sending a message to see if a “Translation” label appears on the message bubble
2. If no response for a long time, manually refresh the current conversation window
3. If still ineffective, try closing and reopening the conversation

Troubleshooting Step 7: Final Checklist Before Contacting Technical Support

Before contacting customer support, verify the following checklist point by point—this can greatly improve problem resolution efficiency.

If none of the above works, submit a ticket via the bottom left corner of the console or contact @tgstaff_robot, and attach:

• Screenshot of current subscription
• Screenshot of translation configuration
• Self-check list results

FAQ

Q: AI translation suddenly stopped working, but it was fine yesterday. What should I do?

A: The most common reason is that the daily translation quota has been used up. Log in to the TG-Staff console → “My Subscription” to check today’s quota usage. If it’s exhausted, wait for the next day’s reset or upgrade to the Pro plan (unlimited translations).

Q: I enabled translation, but the English messages I received were not translated into Chinese?

A: Check the translation direction settings in the conversation window: Is the source language set to “Auto-detect” or manually set to “English”, and the target language set to “Chinese”? If the source language is incorrectly detected (e.g., English mistaken for another language), manually specify the source language and retry.

Q: Why wasn’t the translated message sent to the user?

A: Two possible reasons: 1) Content moderation (Pro) blocked the translated message; check the “Trigger Log”. 2) The translation process timed out; try refreshing the conversation or resending. If blocked by moderation, temporarily disable the corresponding risky phrase verification.

Q: Can AI translation be used during the free trial?

A: The free trial includes Standard translation quota (see the console prompt for details). It works normally within the quota. If translation doesn’t work during the trial, first check if the quota is exhausted.

Q: What languages does AI translation support?

A: TG-Staff’s AI translation (Standard) supports major languages (Chinese, English, Japanese, Korean, French, German, Spanish, Portuguese, Russian, Arabic, etc.); Pro additionally supports Google Professional Translation and DeepL Professional Translation, with broader language coverage. For the full list, see the official documentation.
