You have another DNS server running on port 53, and pihole-FTL cannot bind to that port.

`[53] is in use by named (https://docs.pi-hole.net/main/prerequisites/#ports)`

> Excellent! Thanks so much, this fixed it. I've also disabled named. One thing that I am curious about: why did pi-hole work before the upgrade, and then stop after the upgrade? I'm pretty sure that named has been running on port 53 all of this time.
