qbittorrent 502 bad gateway

Post by juggernaut07 »

I have only a few apps installed via the App Center, one of them is qBittorrent. Recently I became unable to load the app, every time I try to open it I get a 502 error. I tried disabling the app which fails, I also uninstalled it and installed it again but get the same error.

I don't see anywhere to look for logs for Apps installed through the App Center, nor can I find the config file to try and change settings for the App or to back up the torrents within it.

How can I resolve this?

Same here on F4-424 Pro with 6.0.794 TOS.

Hello, we have released the new version 4.1.19. Please delete the old version and configuration files, then download and install the new version again.

This error keeps happening even with new versions. I have 5.1.4.2 and I keep having to uninstall and re-install every few days.

Could be related to this topic : viewtopic.php?t=9714

Check the "Service and Process" in the Settings menu and look for a high CPU load of Qbittorrent.
