Cellular data providers tend to block inputs, especially IPv6. I got WSASendMsg() failed: 10022 when connecting to my desktop using cellular, and found that cellular providers' firewall is blocking sunshine's control stream. When WAN Encryption is opened, the control stream passed the firewall, but another problem appears: the server sends an ICMPv6 to the client's 48000 port, which is intercepted by firewall, thus causing this error again.

I guess avoiding unencrypted data will solve this problem.
Moreover, I also tried VPN softwares like WireGuard and OpenVPN, they are all blocked. The firewall maybe only allow web connections, so I have tried that VLESS worked in this situation. I'm trying to route Sunshine's connections over VLESS now.
