Seems like a change from Web WC server. Can you confirm if you can access Web WC via a browser?

[FlechazoPh]

Yes, web wechat is ok, and It is normal to scan the code again to log in. Can any middleware cause this problem?

[blueset]

Patch Middleware might be relevant, as it directly modifies the code of EWS. Maybe try disable it temporarily to see if it helps?

[FlechazoPh]

I will try to disable it and see if it helps, (but the Patch Middleware is useful...)
