Community ManagerHi there, @DerJohannesMai.
Do you happen to have a Windows PC you can run the UO Trace on? It would be interesting to see those results as they are more detailed. The test results you're providing are showing an issue with the node in your neighborhood. It's timing out. That would be under the control of your ISP. Did you already try alternate DNS settings? If not, those instructions are here. If you don't see a difference, try the Google DNS servers. Those are: Primary alt number 8.8.8.8 - Secondary alt number 8.8.4.4.
