grafana-server service can’t be started by unknown reason. The error message is “permission denied”. But permission seems to be OK.

Could you please tell me what is the problem?

Hi @gont,

Welcome to the :grafana: community forum !!

Not sure if you are still having this issue or already resolved it.

You can have a look at the documentation on how to troubleshoot the Image rendering plugin.
