We’re looking into this issue at the moment. What client revision (shown in main menu, lower right corner) are you on, and which region?
Thank you. We have identified the issue with our server provider and we are deploying a fix.
Current ETA until servers are back online: 30-45 60 minutes.
We’ve posted an announcement on Social Media, reposting it here too:
Servers have received their distributables and should be starting showing up in the next few minutes. EU servers will be the first ones to show, with US and rest of the world to follow shortly after.
TLDR: Servers have received the newest files and will start showing online. Keep in mind that some servers may show up earlier than others depending on the size of their database.
