Hello. I read that connecting to AirVPN using port UDP 53 instead of UDP 443 is a way to get better speeds, but when I tried to do it today it could not connect to that port on any server and kept giving me an error. This happened on both my phone (connected with Wi-Fi) and PC (connected with ethernet cable) . I contacted my ISP and asked them if they were blocking any ports, and they said they were only blocking ports 80 and 25. I had the ISP unblock these ports just in case that was somehow the issue, but it was not and VPN on UDP 53 continued to not work. I even tried forwarding UDP port 53 to my devices from my router, but that didn't do anything. However, when I turn off Wi-Fi on my phone and connect to my mobile network, UDP 53 works flawlessly.
Here is a log of me trying to connect to an AirVPN server on port UDP 53 on my Wi-Fi using my android phone and the Eddie for Android app
