Arma 2 OA Server - wrong installed ?

Hello Guys,

to clarify my problem with the most details that I have:

I got a Debian Server and I copied the following files to my rootserver:

AddOns (from my Arma2-Folder)

Dat (from my Arma2-Folder)

Expansion [which includes also AddOns, dat, BattlEye, etc.] (from my Arma2OA-Folder)

I followed the Instructions here

The Problem is that no errormessage occurs and I started Operation Arrowhead but I can't find the Server via "Remote" (where I can type in the IP-Adress). And yes I checked if the port is correct.

I started the server with "./server" without errors. I didn't find the server.

I started the server also with "./arma2oaserver start" without errors. I didn't find the server.

I checked the status with "./arma2oaserver status" which said "the server should be running"

Maybe someone knows the problem?

EDIT: Ports are not blocked

tried removing capital letters from all the file names?
