DNS broken when Wireguard VPN active

[chikuwasuka 0]

EDIT: Seems to currently be working again... but I still don't know if it was a problem on my end or AirVPN's.

At first I thought this was maybe the service being down but it appears to be a deeper issue.

I've used AirVPN for a number of months, but suddenly as of yesterday I can't access most of the internet with it on due to DNS resolution failing. For some reason, I can usually still access this website, even though running "resolvectl query airvpn.org" returns nothing. Other websites time out or fail immediately. If I run "resolvectl monitor", I can see timeouts, maximum attempts reached, and refused connections.

I use systemd-resolved on Linux as a DNS resolver and haven't changed anything about my config recently; it hasn't updated recently either. For my config I use the client generator and copy the config file to /etc/wireguard/, because I could not get the AirVPN suite to work when I tried it ages ago. Here is my config:
 

[Interface]
Address = 10.129.110.36/32,fd7d:76ee:e68f:a993:1d7b:7f05:c3fe:9ea5/128
PrivateKey = [REDACTED]
MTU = 1320
DNS = 10.128.0.1, fd7d:76ee:e68f:a993::1

[Peer]

PresharedKey = [REDACTED]
Endpoint = america3.vpn.airdns.org:1637
AllowedIPs = 0.0.0.0/0,::/0
PersistentKeepalive = 15
