Recently we made a change to a set of IP's that improved performance. We made a post about it and its visibility was not enough, we apologize for that!
All servers hosted in Europe at the IP 126.96.36.199 have now become 188.8.131.52
Your port does not change for this.
To make this easier in the future we have added a host name to these IP's. This host name is titan.guildlaunch.net with your same port again. This will make it easier for users in the future because we will update our end and the host name does not change.
We will be trying to improve the communication of this if it comes up again!
