THIS SESSION HAS BEEN INACTIVE FOR TOO LONG. PLEASE REFRESH THIS PAGE.

Nobody has claimed this yet.

The timeout is too fast, it will prompt “THIS SESSION HAS BEEN INACTIVE FOR TOO LONG. PLEASE REFRESH THIS PAGE.” soon

I don't know if modify config file: fastchat/constants.py can solve this problem?
```
# Session expiration time
SESSION_EXPIRATION_TIME = 3600
```

# 临时解决办法
我现在进行了临时解决办法，就是将web的老版本，比如运行老版本的 v0.2.7 这个版本，Web就比较正常。
pip3 install fschat==v0.2.7
所以Web段我用老版本的跑是比较正常的。

Start with fastchat/constants.py and the gradio_web_server entry point, then compare the current behavior with the reported v0.2.7 behavior. Reproduce the session-expiration prompt using the supplied launch commands and logs; done means the web session no longer expires prematurely while the intended expiration behavior remains intact.
