SABnzbd stuck on "Uploading" NZB

What type of hardware are you using: Virtual machine
What YunoHost version are you running: 12.1.39
How are you able to access your server: The webadmin

Describe your issue

Hi!

I have a fresh install of YunoHost on a Debian 12 VM on Proxmox 9.1.1, with DNS and port forwarding on my registrar (Scaleway) and my UniFi gateway properly configured (as far as I can tell) for reaching my instance through 2 domain names with Let’s Encrypt certificates.

One of my issues is with SABnzbd (version 2.1~ynh1). I can access it through it’s own subdomain, I can access the web interface, but when I try to add a NZB file, it stays indefinitely on “Uploading 1…”.

What should I do to further diagnose the issue and fix it?

Thank you in advance!
