Since my university uses DPI to ban any website even remotely related to games, I used to use the Stealth protocol of Proton VPN to connect to them in the past.

The thing is that it's stopped working recently but only on desktop, I can still connect fine on mobile when I'm on college WiFi... So what do I infer from this? Is this a bug from Proton's side or did my college figure out how to ban stealth protocol as well? But if that was the case, I shouldn't have been able to connect on mobile either, right?

Should I try contacting Proton support regarding this?
