I'm running Mullvad using wireguard (wg-quick) on a Raspberry Pi, and it has been working great for the past several years. This morning around 6 hours ago, for no apparent reason, all my outgoing and incoming stuff on Homeassistant stopped working, that's how I noticed something was wrong. Rebooted the Pi but to no avail. Trying to ping just gives me "temporary failure in name resolution".
Doing "wg-quick down mullvad" solves all connection issues but obviously this is not what I want.
I have tried generating new keys and config files but no luck.
Pinging the DNS server 10.64.0.1 from my non-mullvad-connected PC times out. So my best guess is the DNS server went offline this morning, but there is no info about that on Mullvad's server status page.
Any suggestions on workaround? Can I just replace the IP address in the config file with 194.242.2.2 (mullvad public DNS)?
