openclaw - 💡(How to fix) Fix Bug: Gateway WebSocket handshake fails with token_mismatch on Ubuntu Kylin 20.04 [1 comments, 2 participants]

TL;DR

The most likely fix is to investigate and resolve the token mismatch issue causing the WebSocket connection failure between the Web Control UI and the gateway.

Guidance

• Verify the token generation and validation process in the custom model provider (zai/glm-4.7-flash) to ensure it matches the expected format and content.
• Check the gateway logs for any additional error messages or clues that might indicate the root cause of the token mismatch.
• Compare the configuration and setup of the custom model provider between the working version (v2026.4.11) and the non-working versions (v2026.4.23, v2026.4.24, v2026.4.26) to identify any potential changes or regressions.
• Test the WebSocket connection using a tool like curl or a WebSocket client to isolate the issue and gather more information about the connection failure.

Example

No code snippet is provided as the issue does not contain sufficient information to create a relevant example.

Notes

The issue seems to be related to a regression introduced in version v2026.4.23, and the custom model provider might be a contributing factor. However, without more information about the provider's configuration and setup, it's challenging to provide a more specific solution.

Recommendation

Apply a workaround by investigating and resolving the token mismatch issue, as it's likely the primary cause of the WebSocket connection failure. This approach allows for a more targeted fix rather than upgrading to a potentially unaffected version.
