If you see “Connected to 1.1.1.1” = yes, then can you run the following command: dig +nsid CHAOS TXT id.server @1.1.1.1 and provide the output of that please
Max, thank you for your response.
Things are working fine again today. If this problem recurs I will use the provided diagnostic link.
Unfortunately, since I had to switch resolvers yesterday afternoon, I can not tell you when things started to work again.
So we can close this case. thank you
