Log errors "doh resolve: context deadline exceeded"
I have recently started to see groups of entries like this quite often in logs. Any clue what's happening?!

Did some digging myself and seems to be the UltraLow PoP "ipv4-edis-cph-1.edge.nextdns.io" on 192.36.27.86 that don't perform good. Every time the CLI switches to it, these errors begins and it switches back to 188.172.192.71 but after a while it's back again.
Two samples that occurs all the time now:

My route to 192.36.27.86 seems OK (skipped the first 4 hops due to privacy)
