Hi @umlumpa Thanks for reaching out. Firstly. What image is that nginx-unit:8.0? It is not our official image and I just want to make sure you are aware of what Docker Image you are using.

Re your issue. We need more information to even guess what the issue will be.

What user is UID 101? Is that Unit? Please share your Unit configuration. What kind of Application is that? PHP?
