All nearest Cloudflare nodes seem to be operational, according to Cloudflare status. Looks like the images try to load for 15-16 seconds, and then just throw 522
The first two thumps also show up as cancelled
I'd try a different browser, but seeing how it's an issue with an API via an Android app as well, I don't think the result would be any different. Guess I'll wait and see, and report back if the issue persists tomorrow or so ¯\(ツ)
Edit: another 522 occurred when trying to get the kaomoji to work lol
Seems to not be just an issue with the thumbnails and images, but some other issue with CF. It also told me that the node serving the request was in Hamburg, while there is a closer node smack down in the middle of my country.
The initial connection between Cloudflare's network and the origin web server timed out. As a result, the web page can not be displayed.
