All players stuck at "Attempting resolved connection to server"

[Lo Zeno]

As the title says, all my players seem unable to connect to me today. I've disabled antivirus and firewall already, I tried using a mobile hotspot and a VPN, hell I've even used another laptop copying my campaign over and nothing, same issue happens every time. All the logs show is "Attempting resolved connection to server." followed by IPs (v4 and v6), we tried letting FGU do its thing but after roughly half an hour we gave up.
Is there some issue happening on fantasy grounds connection servers?

Another 25 minutes later, the connection issue seems resolved. Too late for our planned game now, but at least everyone connects. We have no idea what changed, all we did was the usual network troubleshooting and it did not solve anything, now all of a sudden everyone connects even with firewall and antivirus programs on.

FYI, as part of troubleshooting one of my players who has a Ultimate licence (let's call him Host2) tried to start a session as a DM and we connected all as players (me included) and we were all getting stuck at "Attempting resolved connection to server" again. Host2 is in a different country than me.
