Hey everyone!

I have a Firewall which block every ports except my list. I've wanted to use Telegram on it but it seems that Telegram uses random ports. So I tried to use the proxy method with a SOCKS5 proxy on port 1080. I opened port 1080 (Both TCP/UDP) on the firewall. The proxy can be reached and is connected. But when I tried to make calls the same problem as if I didn't used the proxy happen -> the call cannot connect (stays on exchanging keys or connecting ... and quit call). So it seems that the Proxy For Call option doesn't work, isn't it? Something can escape my brain but I can't see what at the moment ...

Operating Systems: MacOS 12.1 | Windows 11
Telegram Version: 3.4.3

Thanks for reading and helping

P.S.: Doesn't know if it's an app issue or a something related on my part so can't tell if it's a question or a bug
