I have qBittorrent running on an Ubuntu 24.04 server VM and am having trouble with the virtual network interface that Mullvad uses. On startup I have a "wg0-mullvad" interface which I bind my qBittorrent instance to. I don't know the exact time but after no longer than a day of uptime, the virtual interface disappears and is replaced by "tun0". Running mullvad status returns "Connected to se-mma-ovpn-001 in Malmo, Sweden", and I still otherwise have internet. I can get the interface back by disconnecting and reconnecting Mullvad.
Is there anything I can do to fix this, besides running a cron job to reconnect it every 8 hours or so?
