Those protocols are almost all TCP-only and not UDP. On such networks it's useful to also support TCP connections, even though this is less ideal due to the possibility of the TCP Meltdown phenomenon. But given the choices between something that works reasonably well or not at all, we've chosen to be practical and also support TCP.

TCP is more reliable, so you may think that TCP is the best option, but there are times when UDP might be preferred. There is an option within the OpenVPN application that allows selection of a TCP-based connection, however if you find it becomes necessary to use TCP - we recommend using SoftEther or L2TP (L2TP is a TCP-based client offering flawless connection for mobile devices in particular).
SSL VPN over UDP still attempts to connect to the VPN server on port 443, but unlike HTTPS traffic that uses TCP as a transport protocol, it uses UDP. Some firewalls and proxies may flag this as suspicious and drop the traffic. It can also be seen as peer-to-peer traffic (which it actually is) and again be dropped.
For most VPN users, UDP provides the best option for general use. The typical recommendation is to start with UDP. And if you experience issues with the connection, try the TCP protocol. Some of the potential problems that may keep you from connecting to a VPN with UDP include: Countries or ISPs blocking UDP ports to prevent VPN connections TCP vs. UDP (In-depth Look) So what is the difference between TCP and UDP, exactly?
