I'm getting this error that says Error. I can't tell if I fat-fingered the community name in the URL, or it got removed, or it doesn't exist in the first place, or maybe there's a legitimate issue with the software, but I hope it's useful!
I need to clarify because some people apparently never encountered the error page: it used to show the actual error. It was later changed to not do that.
(apologies for the atrocious aspect ratio)
I assume this is in a browser. You might have more luck checking the network protocol. Press F12 (Windows/Linux and Firefox/Chrome; don’t know about Apple) to open the dev tools. Open the network tab, and retry your request. One of the new lines in the log should be red. Click that and check “Response”.
