Our customers from Russia report that WireGuard with port 53 suddenly stopped working on a mobile network. At this moment only with two operators MegaFon and Yota.
There are two possible scenarios:
1. Technical issues on MegaFon and Yota side2. The Russian government is trying to block access to VPN
Either way, other ports (51820, 80, and 443) are working normally. We recommend our customers generate new configuration files with another port.
 After this incident, we took measures and changed the default port to 51820 then generating new configuration files.
