phpmyadmin 500 internal error

[nadav123]

Hello Everybody, first, i attached the screenshot of the problem be much easier. (500 internal error)

I open port 3306 on CSF (is not needed because we do not actually have access from this port, even the cPanel security advisor recommended turning it off)
this is because CSF does not open this port, CSF is very matched to cPanel.

After this does not work,
I even turn off the firewall (CSF)
and
generate the default my.cnf. by deleting him and re-install MariaDB 10.5

sometimes PHP my admin in whm get this error.

I was suspect on MariaDB 10.5 and UNIX_SOCKET=OFF the installation put by default in my.cnf
but
i try to uncomment the rule as well and this didn't help as well...

I have another cPanel with Mariadb 10.3 the problem is not accurate. this is why i suspect on MariaDB 10.5 himself.

btw:
I upgrade from MySQL 5.7 to maria DB 10.5 on a new server.

another thing is
restartsrv_cpsrvd:

https://support.cpanel.net/hc/en-us/articles/1500000292721-WHM-cPanel-phpMyAdmin-Internal-Server-Error-500-No-response-from-subprocess-php-

this because i notice until cpsrvd not up, error not accure.
when all the server finish the reboot,
and
cpsrvd is up and active, problem accure again like the screenshot i attached.

Is someone here familiar with the problem?
