I am just migrating from domoticz to openhab and have a question regarding the usage of Pi-Hole and openhab on one rpi4. I know this is not how it should be, but for the time I need my other rpi to run my old domoticz install.
Pi-Hole fails to start the DNS Service with this error
FTL failed to start due to failed to create listening socket for port 53: Address already in use
Is openhabian using port 53 for some other cause? And how can i get it to stop.
It will only be a temporary solution.
Tank you for your help.
