I see an error but have no clue where to look.
Anybody can give me a hint?

Is this the first time you install Domoticz ?
means a service or a program is already using the same port on your setup.

maybe you have started Domoticz 2 times ?

Kind Regards

I'm using domoticz since 2017 and installed it already many times. Just can't imagine how it starts 2 times after a clean reboot. Could it be a plugin/ extention in the browser?

I've seen this the moment another occurence of Domoticz is running with same remote shared port (see settings, tab security).

Thank you this solved the issue. Changed to another port.
