It's dissolve, this topics may be same problem no DNS.

I try create own OVM wiki with zim wiki. I want to shared OVM experience for my friend later.

When we install plex media server in plugins, It's not require to install in docker right?

I see many video tutorial showing how to install transmission in Docker. Currently on OMV 4 we can install from plugins without install from Docker?
