^^ Config

When I installed Community Bridge on my server, I restarted and edited the config with the proper database information for my remote MySQL database for my web server. I'm running it with Xenforo. When I restarted the server after editing the config file, it gave me the above error in the log. Both servers are run by the same hosting service but I'm unsure if they are on the same box or not. I also put in a message to my host to see if the issue is on their end, but I can't figure out how to get it to connect. I also allowed remote connections from the IP address of the game server (without the port) if that means anything...

This message means that the Minecraft server's address is not on the MySQL server's allow list. Make sure the username is allowed to access the database from that IP/DNS.

On the upside, getting that message means that the MySQL server responded to the connection...it just doesn't know whether or not to trust the MC server. :)

Could not connect to MySQL Server:null,  message from server: "Host 'static.88-198-9-201.clients.your-server.de' is not allowed to connect to this MySQL server"

You should change your MySQL password...it is published in your pastebin of the configuration.
