Hello, recently and more often having problems with users while browsing on sites with QUIC protocol enabled, the problem is with mobile users, accessing other services like discord or using brave browser is not an option, since it is a guest network, any suggestions to bypass or solve this issue? I have seen that udp port 443 must be blocked to avoid having the ERR_QUIC_PROTOCOL_ERROR error
I solved all of that plus more, by blocking UDP port 443. Then browsers fall back onto TCP HTTP, and they also are no longer able to circumvent many of protections in place against backdooring, dialing home, etc.
