Issue with Pi-Hole on Ubuntu and port 53

[RamSet]

@Steven_Lloyd

Shows me a service called “named”

That's exactly what's taking over port 53 (required for DNS0 and not letting Pi-hole use it.

See:

FTL offline - Lost connection to API

Here you go: https://linux.die.net/man/8/named This was installed as part of some other software (not a part or requirement of Pi-hole). You can either configure named for a different port or remove it (but this might have implications further down the whatever installed it in the fist place). Pi-hole required port 53 in order to work and if that port is not available, it will behave like it does in your case.

That should fix your issue.
