Expected Behaviour:
I shouldn't get error messages.
Actual Behaviour:
- I get error messages in the diagnosis pane:
- I can't access some websites: www.postfinance.ch for example.
It happens when I change my DNS upstream resolver as well.
Checked open ports: Prerequisites - Pi-hole documentation
They are all open, port 53 seems to be reserved for DNS, modem refuses to open it manually.
I "fixed" it by disabling IPv6 upstream servers. But what does that mean in the long run? With Pi-Hole 5.x I dindn't have those errors.
