PhpMyAdmin sudden timeout

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

CentOS Linux 8.2.2004 (Core)
Plesk Obsidian Version 18.0.31 Update #1

PROBLEM DESCRIPTION

This is in all plesk versions. Login in plesk and pick a subscription and go to database -> phpmyadmin. Working in phpmyadmin for a longer time and you get a message box with error code 400 Bad Request (rejected). Its a time out. Because ajax call /phpMyAdmin/sql.php returns 400.

For security reasons there is a timeout. That's a good thing! But why do I get this timeout if I called a SQL query successful only one second before? Shouldn't the timeout for activity be extended accordingly?

Is this a setting from plesk or a phpmyadmin thing?

And why error 400? Shouldn't it rather say that you were automatically logged out?

I have experienced something similar on Obsidian. The cause was that I was logged out from the panel. When you are not logged in to the panel, subsequent requests through phpMyAdmin fail, because phpMyAdmin is no longer authorized to access the database. So this might have something to do with the session expiration of your panel login.

It is related to the Plesk session timeout. The workaround is to increase it in Tools&Settings > Session Idle Time.
We should adopt the error message and show that it's an actual timeout. Bugreport PPPM-12565 was submitted.
