Does anyone have any experiences with solving "DNSv4 error: no answer on DISCOVER" with a Fritz!Box? (I have the 5690 Pro in favor of the one provided by the ISP) We have internet via fiber (Hiper is the ISP and TDC is providing the fiber connection with a box on the wall).
We have received this error before. Previously I could resolve it by using DNS over TLS, but it doesn't help this time.
The problem started after a router firmware update, but I would prefer not to rollback if possible.
