Linux service not starting?

Question

linux

Gives this error when trying to start the service.
The directory is correct, manually through "dotnet ......" it works.
The user has rights. The group does too. Tried with different users and directories.

What could be wrong

Answer 1

I don’t understand anything in these dotnets of yours, but how does Linux know exactly how to run this dll that you slip into it in the launch line. Where is the command to run this dll ?

Answer 2

manually via "dotnet ......" works.

What command do you run manually?
