Solved Login into Cloudron dashboard for normal user not possible during backup task
My prometheus is doing a backup task. During this task it's not possible to login as a "normal" user. Not possible means: after the login you're redirected to my.example.org/#/apps and nothing happens anymore ("white screen of death"). If you go into your browser developer tools (network) you can see a 403 for (in my case) file 6686 (/api/v1/tasks/6686). If I switch to a user with admin role, I see a message for this file "Backup - Uploading backup 50M@5MBps (prometheus.example.org)".
The moment I cancel the backup task, everything works as expected.
Good catch, looks like the dashboard needs a fix for this. Will investigate.
Fixed now. Will be part of 6.2 then I guess.
