LDAP won't connect on one server, but it will on the old one

Hi there

I had some issues with agents and decided to completely reinstall my OS and Icingaweb2.
However, I can’t get LDAP to connect on the new installation, but it works perfectly fine on the old one!
I already checked almost all settings, and they’re identical!

Running on Apache 2.4.37 (CentOS8) on both instances

The LDAP config is correct because it works on the other VM…

Latest version of everything because I only just installed it.
