Solving a permissions problem

[ExtremeNoob]

Hi! I'm getting a message when loading the handbrake stack with portainer;
[nginx] nginx: [alert] could not open error log file: open() "/config/log/nginx/error.log" failed (13: Permission denied)
Being a noob, I installed and run omv as root. Is there a troubleshooting method for this kind of situation? Since the container doesn't start, I can't attach a console and inspect it from the inside. I was trying to find the permissions for nginx and apply them to the folder in question, but so far, no luck.

Thanks!

Can you share more details on how you created the container, what is its configuration ?
