Hi there, Any reason you have unix as protocol? Groetjes,

[cpktmpkt]

to be honest, no. i just followed any tutorial so far and do not have any problems before. But I switched from an bare mateal Alpine Linux installation to the docker image and lust copied my config.

what should I use instead?

[djurny]

Hi there, Would advise to use udp4 or tcp4 as it seems there might not be domain socket support for writing to syslog in your Docker env. Or leave it out from your config to have z2m use default protocol setting for syslog. Hope that helps, Groetjes,

[cpktmpkt]

thank you. A change to udp4 let the container start again without errors
