Sometimes the VPN refuses to connect to the selected servers
So, overall, I wanted to frame the post more as a question of "am I the only one experiencing this?", but I decided to add a couple of my observations as well.
Sometimes, regardless of internet quality, the application AdGuard VPN stops connecting to absolutely all available servers. This lasts from approximately 15 minutes to an hour, after which it functions normally. Any selected server will display the message "waiting," and the failure will occur simultaneously on all devices (I tested a smartphone and a laptop, and both showed the message simultaneously) and on different networks: mobile internet and Wi-Fi.
Let me tell you right away that I'm from Russia and I know about constant blocking from government, so I'd like to know if this is a widespread glitch, what it's related to, and whether there's a way around it.
