@quuuuu see that 651ms? i bet our problem is the same. You have about 72ms, i have 63 ms, all of a sudden yours go up to 651 ms and mine goes up to 508 ms. i trace again with open visual traceroute and i discover that it goes from portugal to france, but it goes and come then from usa. dunno if the higher pings have to do with this atlantic connection. My connection "reconnected" twice while i was writing this post. It would be cool if more people could testify about their connection to pinpoint what the problem is. What kind of connection do you have @quuuuu (adsl, fiber, 4g)?
That 3 failures in your ping must make any game to disconnect. That's the proof that your connection with lichess.org is not allright. Try to ping sapo.pt for example. It is a portuguese site, very reliable, if it gives you a constant ping... Anything is wrong with lichess connection.
You can't post in the forums yet. Play some games!
