Webui don't load any torrent

[grechk]

I use arch linux with qbittorrent-nox.
The web interface does not load the central part, that is, the one where there is the list of torrents. This only remotely, because if I access from the local network it loads correctly.
I have had this problem for a few months, without having changed anything. I tried to downgrade the version, in sequence I tried 5.0.1, 5.0.3, now I have 4.6.6 (which worked correctly).
Before I had installed jackett, now I have removed that too.
I have attached the screenshot of the interface loaded remotely.
I don't know what to do anymore.
Thanks

Check your browser maybe? Try different one(s)?

I tried on different browsers, on different Linux systems. I don't understand why it works on the local network but on the same computer and same browser connected remotely it doesn't work.
I thought about some router settings, maybe it was updated and since then the problem happened but I don't know what to look for other than port forwarding, upnp, and various remote access settings.
