My ping wasn't even high. It was like 11-14 during both matches I just played. Still, the first match was "unstable connection" throughout the match, and the game was very stuttery, with delay being over a second at the worst points. Second match, first half was OK, no problems, second half unstable connection again and I nearly lost a 4 goal lead because the game started to get so unplayable for me. I don't usually get this at home, only when I play somewhere else and use my mobile data connection. Despite it being a 5G 300M connection, it sucks for gaming most of the time. And when I use that, the ping is bad too. Like 50-90ms. But now the ping is supposedly good, but still the game is almost unplayable?
But now it's happening at home on my fiber connection..? Must be a server issue?
