Session expiration for login in WHM and webmail

[Farshid928]

Hello

A bunch of our cPanel servers (8-10 servers) have trouble logging into WHM and webmail (port 2096)
The issue started with cPanel being completely unresponsive on port 2096 for webmail. I tried updating via /scripts/upcp --force and it fixed the issue for a while but now we have session expiration error while logging into WHM or webmail.
I'm puzzled as to what's going on because it's not just one server. All servers are running on cPanel v90.0.10 on CloudLinux 7.8 or CentOS 7.8.
Is anyone else having this issue? Is this a cPanel problem or something fishy is going on our servers?

I'm not aware of any session issues at the moment. Can you provide an image or text of the full error you're seeing? Is there anything in the cPanel logs at /usr/local/cpanel/logs/error_log when that issue happens/
