Error messages when using homegear as docker container

Hi

started using homegear with docker (stable branch - self build according to readme).

So far all flows and functionalities are working like they worked before on native installation.

Nevertheless I see some error/warning messages.

I’m running:

Linux lemonpi 4.19.97-v7+ #1294 SMP Thu Jan 30 13:15:58 GMT 2020 armv7l GNU/Linux

homegear -v

homegear-webssh.err

04/14/20 11:43:20.903 Could not connect to socket. Error: No such file or directory

I think the ones from webssh are because of running homegear inside a container
for the ones in homegear I found some mentioning inside the forum, but no real conclusion.

As mentioned, looks all is running ok, but curious what it means.

cheers
