As a wish of Merry Christmas, I remember only a month ago they casually shutdown all their services leaving nginx error as their website main page. I didn't have anything critical there and they got to "normal" after about 2 weeks but it made me visit this topic again
To the topic starter, if you got time, you can wait for a few days, maybe they would fix the issue. If not, you can try moving to another cloud and see if it helps, usually it does.
UPD: currently I can't sync to tab.digital as well (time out error 504), so they might be at it again
