I'm not sure how long this has been going on (my feeling is quite a while), but I am no longer able to join games by clicking on them from the My Games page. I have been joining games by using my browser history, but I rebooted my computer and now cannot do that.
When I do click on a game, I am brought to the game page but no graphics or page elements are displayed. I can see the page address in my browser, but the loading progress bar continually cycles back and forth without ever getting to the actual game.
Some of the games I am having trouble with are Crusaders of the Lost Idols and Astroflux. However, it appears I cannot connect to any of the games in the My Games page I have (about 25 games -- I haven't tested them all, but I couldn't connect to the first six I tried, so it seems there is a strong pattern there).
I am using Safari 11.0.3 on a Mac running 10.12.6. If anyone needs more details to help solve this problem, please let me know and I will help however I can.
