Firefox VPN not working at all

I am attempting to use Firefox's new built-in VPN to hide my browsing and use sites that are restricted like Reddit on a common wifi while I am on breaks. It worked on these common wifi systems for a little bit, but last week I believe, it just stopped working one day. Now, when I turn on the VPN, the only thing Firefox will do is display the following error: ~~~~~ Unable to find the proxy server

Firefox can’t connect to the server at [insert url here] What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi. ~~~~~ I was originally running Firefox 149 via snap on Ubuntu, but I just uninstalled the snap package and switched to 150.0.1 via the Mozilla APT repository and I am getting identical behavior. Is this just a bug, or is it possible the administrator here has explicitly blocked Firefox VPN? Is there anything else I can do about it, since connecting on a different device doesn't help me, I can't check the modem or router, and disconnecting and reconnecting does nothing?
