Was that just before you posted or earlier today? I have seen some other topics with Live server issues earlier today.
It is possible to lose connection to the Live server process but other parts of the site to load fine. Most of the time a refresh will reconnect when that happens. I have had it happen in the past that closing the live tab and getting back in would work. I understand you tried that and it is very possible the live server was experiencing problems at that time.
I was inactive on this website for over a year because I found what I consider to be a much better chess-provider.
Recently I decided to give chess.com another try and came back.
Unluckily, I have been kicked out my games already twice today and lost two games where I had a winning position.
Everything with my connection was fine- as soon as I read that I had been disconnected I tried to open facebook and other websites and it worked. The connection was there. I tried to refresh the tab with my match but it didn't reload; within the span of the following 50 seconds I then went on the homepage ofchess.com and clicked on "Forum", "Learn" etc, and every link opened, but as soon as I tried to get back to my game it wouldn't load anything at all.
I think this situation speaks by itself.
