Try to check more error details in the application server logs. It could be a database connection issue or a performance issue. I would recommend to check your confirguration of the record.

The best way to check the exact error are the logs.

I've seen this before with custom authentication and session timeouts. I just ignored it as expected behavior, but it would be nice to have something more user friendly.

You should open up a support ticket, but If you're not using one of the supported Auth methods (SAML, LDAP, etc), then you might just have to train your users to expect this.

I checked the logs, only find below error might be the root cause, anyone see this before? BTW, the timeout error only happened in a task form
