I have the same problem!
Downloaded the game for some days ago and played some but some days after I got this. So if you know what to do im very pleased if you want to share it with me too!

just found the known issues thread and this helped me out:
1. Error: Servers are showing as offline
- Add launcher.exe / patcher.exe / elementclient.exe to your antivirus exception list
- Run fixit.bat in EPW/launcher and then click 'Verify' button on game patcher
- Make sure that your serverlist.txt file in EPW/patcher/server/ looks like this (edit if it's different):
Code: [Select]
EPW
Epica 29000:5.39.64.173
