Zigbee2MQTT wont start after chanel change from 11 to 20

I changed my home router to chanel 1 and my Zigbee2MQTT to chanel 20 so there is no interferiance. However, after I did that and restered home assistant all my devices were unavailable. I know I have to repair them. BUT

My Zigbee2MQTT interface wont start and gives me “Bad gateway”

This is the log in Zigbee2MQTT addon:

And here is the configation, it was working gine until I changed the channel from 11 to 20.

PLEASE HELP? How to do I get it back online with the new channel 20? I know I have to repair all my devices but I cant get to there :frowning:
