I guess the Rocket League tracker is just offline right now?
So far, I’ve only narrowed it down to Google Chrome. Any other browser I’ve tried seems to work fine. My personal workaround, whence is to just use Firefox for tracker.network I’ve yet to try if this happens on any other machine, or with a blank profile.
With Chrome pretty much any user page on the rocket league tracker is affected. So are the leaderboards. Ranked Duel 1v1 Rating Leaderboard - Rocket League Tracker
Also not all games seem to be affected. For example I get 400 server error on Battlefield V player profiles. Destiny 2 profiles are an example of it working fine though.
Damn, Privacy Badger seems to have blocked something it shouldn’t have. Sorry for all the noise.
