Does Stealth Port not work with UDP? Only TCP?

Question

I'm just wondering because Port 4443 now says "ObsTCP", but you are able to select UDP in conjunction with that as the protocol when using VPN, so I'm wondering if that breaks the functionality of using the Stealth Port? My assumption is...maybe? Because the internet at large uses TCP, so using Port 4443 and UDP wouldn't have any additional benefit in bypassing certain blocks? Just a guess. Hopefully someone can let me know either way, thanks.

Hey there,

If you have the stealth (shadowsocks) option checked under the connection details screen (burger menu on top left) then this will only support TCP but unchecked you can still use the obfuscation offered on port 4443 TCP and UDP.

Understood, thank you. I never use the "Enable Stealth" option for shadowsocks because it never works for me. It just results in an endless of connecting, then momentarily connected, then disconnected, and rinse and repeat. I see "Enable SSL" is also only available on TCP and I believe that to be Stunnel, correct? Good to know that we can use the obfuscation afforded by port 4443 on both TCP and UDP though.
