Hello, I have a problem with Wireguard DNS proxy.
Issue looks like:
Trough DNS proxy
$ host presence.teams.microsoft.com.
Host presence.teams.microsoft.com not found: 2(SERVFAIL)
Trough the upstream DNS server:
$ host presence.teams.microsoft.com. 10.10.10.1
Using domain server:
Name: 10.10.10.1
Address: 10.10.10.1#53
Aliases:
presence.teams.microsoft.com is an alias for presence.services.sfb.trafficmanager.net.
presence.services.sfb.trafficmanager.net is an alias for a-ups-presence0-prod-azsc.eastus2.cloudapp.azure.com.
a-ups-presence0-prod-azsc.eastus2.cloudapp.azure.com has address 52.114.142.202
Logs from server:
