ExtDB2 Error w/ Database Connection

[4n0nh4x0r]

I get everytime the same error message.
"Call extension 'extDB2' could not be loaded"
"extDB2: Error with Database Connection"

I dont understand the Link function (I put the link as plaintext in there.)

185.188.7.165/arma3server-console.log

I'm extremely pissed of by this because we already had a working arma 3 server.
The OS we use and used is Debian 8.

We installed the server with LGSM (Linux Game Server Management) if this can help to solve the mistery.

Help me, GitHub. You're my only hope.
