And here's what I see when I follow the link:
Just yesterday, the desktop version of the app was released (
https://t.me/tonstationgames/635). I've been testing this version a bit, but it's not going smoothly yet. For example, I couldn't access the wallet address binding menu. In general, the desktop version is working.
However, I also had the same problem as you. It seems to me that this is related to the Internet, and not to the application itself. Because the exact same problem happens with other Telegram apps. I'm not sure, but maybe it has something to do with blocking access to websites? Now the authorities of many countries are very fond of banning something.
The main thing is that now, when a visitor to the forum clicks on the signature, the desktop version starts (of course, if the Telegram desktop is installed), and he does not need to scan QR from his smartphone.
