I recently started using Twingate on my F36 box and I’m having an issue where after some time, all DNS queries begin to lag and fail. It takes around ~10 minutes post connection for the issue to arise. Here’s what I’ve got from the logs:
Sep 7 09:23:02 Lappy twingated: [msg] Nameserver 192.168.1.1:53 has failed: request timed out. Sep 7 09:23:02 Lappy twingated: [msg] All nameservers have failed [root@Lappy log]# telnet 192.168.1.1 53 Trying 192.168.1.1... Connected to 192.168.1.1.

[root@Lappy log]# NetworkManager -V 1.38.6-1.fc36
As seen above, Twingate says my DNS server is down, but it’s clearly still able to resolve queries, though NetworkManager is not.
Any ideas what may be causing this?
