Cannot join Server when using 25+ Mods

Hello,

We have a Server running with a collection of 37 Mods.

When trying to join said server it refuses me to even try to connect (Pressing "Join Game" does nothing) and it also does not show the "Experimental" Icon at the server.

Friends can join the server Fine without a problem, it only happens to me.

When trying to view the Server Settings in the Server Browser, it states "Error Downloading Server Settings".

We've went hunting and removed mods one by one, until we had about 24 Mods left, which then allowed me to join aswell as seeing the "Experimental" Icon.

After adding a 25th Mod, it didnt allowed again.

The Content of the World seems to be unrelated since we also tried using a new World, but resulted in the same.

I will be attaching the Server config without Passwordsalt, Client logs aswell as screenshots of the Issue.

What i have already tried;

Reinstalling the Game

Completely wiping "%appdata%/SpaceEngineers"

Using another DNS like 1.1.1.1

If more Things are needed I'm happy to provide them or try most things.

I am using a small bit unusual Network Setup with a own DNS Server run by PiHole, I am unsure if it may be the source, but it shouldnt be
