Hello,
So to verify that I understand your situation,
You are unable to login to s1208, s1230, and s1232.
You are able to login to s17.
Other people are able to log YOUR account into s1208.
Other players are able to log into s1208 (I verified this).
All listed servers are European servers.

Is that correct?


What region are you geographically located in?
What region are your friends geographically located in?
Have you attempted to login to the game using a different ISP?

Please let me know, thanks!

Would you say that your internet connection in the office is better or worse than your internet connection at home? Also, would you say that your internet connection at home is good or bad? The reason I ask is because it sounds like you're having a problem connecting to the server that is caused by both a local side and the server side being out of sync. This is, unfortunately fairly common, bust most people's connections are robust enough to handle the small amount of desynchronization. The problem is magnified if a player's local connection is particularly poor, however, and we see a situation where other individuals can log in just fine, or other people can even log into their account, such as what you're seeing. This c*so be magnified by being outside the region in which you're playing, and is usually resolved by using a VPN and setting it to the region in which you're playing.

Since you're able to log in using your data plan, that most likely confirms that this is a problem with your internet connection. You have two real options moving forward. You can contact your ISP to see what the issue is, whether it's a blockage on your end, locally, or on their end (whether they're blocking the game, or they're limiting bandwidth), or you can put in a ticket with customer service to see if they can help, but they will most likely tell you to contact your ISP.
