suddenly getting "502 bad gateway" for CWP admin panel

Out of nowhere, I'm suddenly getting "502 bad gateway" on my dashboard when I access domain.com:2030

All the websites work just fine, it's only the server dashboard.

Any ideas what could cause this and how to fix it?

TIA!

Error I get: 502 Bad Gateway

cwpsrv

Nevermind - I ended up restoring a backup to fix it, it's fixed now. Still no idea what caused the issue to begin with.

this should fix it

sh /scripts/restart_cwpsrv

I rebooted many times, re-installed cwpsrv, phpsrv, but nothing had fixed it.

then you need to check the logs to see the exact error you have

try checking the logs or reinstall it
/usr/local/cwp/php71/var/log/php-fpm.log
yum reinstall cwpphp
or
yum install cwpphp
