Is this the web app or desktop app? The desktop add doesn't need internet to function.

[Romanus101]

This is a desktop app. It doesn't need the internet to work, but I do need the internet for work. When I'm using the internet, the app works fine, but as soon as I need VPN/Proxy services, the app stops working, like in the video.

I'd also like to add that the problem wasn't discovered in the latest update, but rather about a year or so ago. During this time, I tried many virtual network services, and the app produced the same result with all of them.

This is interesting, we have tested it working for offline mode, but not with any VPN, need to check what is wrong.
Can you check if it works offline.

[Romanus101]

Yep, even offline if i use VPN app is not working

[abose]

If offline and vpn is not used, then does it work?

[Romanus101]

Yes

So the VPN is doing something funny if it works offline without the vpn.
Let me try out with proton vpn if we can recreate this issue.
