Is the server down because I am unable to sign in. Says Lost connection to the server.

We are not aware of any problems or network outages. No reports by our service provider OVH either.

Interesting. I cannot sign in to Messenger but can access Voobly website without an issue.

Anything I can do to resolve the issue? I disabled the firewall as well as reinstalled voobly. No luck.
Someone inadvertently blocked my ip?

In most cases this is caused by AntiVirus / Internet Security software. Uninstall, reboot, re-install, reboot... that should fix it.

I tried that didnt work. I started my vpn and that let me in. Not sure why it didnt work without vpn.
