PS4. Whenever I try to log on over a wired connection, it tells me “failed to connect to game server. Please try again later.” WiFi can get in but my WiFi is slow and unreliable. I have used this internet all year but this problem just started occurring. Other games like for honor and apex legends work fine. Also I don’t have access to the router because I am on a dorm WiFi.
Sounds like your campus may have blocked some of the ports, either intentionally or via a security program, that allow you to connect to Overwatch. This is very common on school networks, so you’ll likely need to address it with them.
