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?

To update, this problem is not specific to that network. After trying on my home network, on which I definitely have not blocked access, I still got the same behavior.

So this is one and the same laptop, that you connected both at work and at home, and from both locations you only get the error pages — presumably for every address, be it mozilla.org, example.net or wikipedia.org etc.?

Aren't you blocking some cloud provider hosts or IPs on your machine? I'm not sure if there are good tests for the built-in VPN endpoints, that everything's "green", that the service can see its own endpoints, and that DNS resolves as expected etc. … wondering what might be the culprit. Does about:networking show any VPN–related hints for you, e.g. in DNS?

In case you run DoH in "Maximum Protection" you might run into https://bugzilla.mozilla.org/show_bug.cgi?id=2037364 — however this sounds more like the opposite, whatever's necessary to connect to the service is not actually resolving:/
