When urbackup runs as another user webpage doesn't show

Webinterface

Hi There,

As suggested I changed /etc/default/urbackupsrv to use another user.

I’m trying to run it in a lxc with debian 11 on proxmox 7.1-12.

When I change in /etc/default/urbackupsrv USER=“urbackup” the webpage is visibele.
When I change in /etc/default/urbackupsrv USER=“guyf” the webpage doesn’t load

I need to run as another user to write on a mounted path
