I had this problem for two hours. I gave the Games forum link another try a minute or so ago and it's fine now.

Every time I try to get into Subeta Features/Games by clicking on the Games link I get -

Error 504 Ray ID: 4c73c01bc813bfd6 • 2019-04-14 06:52:17 UTC Gateway time-out

If I click on the Item Hunt, Quests links under the games heading I can get to those subforums but clicking on games from the options at the top of these pages doesn't work either.

I can get to the last topic somebody posted in by clicking on the title link. I can also get to the topics I always post in by hunting through my recent posts and selecting go to topic.
