(EDIT: Lemmygrad seems to work again, as of 22:20 UTC on 2022-03-24. The question remains on what to do about it, if/when it happens again...)
I am having problems accessing any page on lemmygrad.ml. First, there is a very long time loading it, then there is the error:
404: FetchError: invalid json response body at http://lemmy:8536/api/v3/community/list?type_=Local&sort=Hot&limit=6&auth=[a lot of letters and numbers] reason: Unexpected end of JSON input
I also encountered the 504 Gateway error quite often today.
The errors don't happen every time, occassionally I can load a page, but rarely enough that I can't use Lemmygrad.
Lemmygrad used to work fine before, and lemmy.ml seems to work still, so that would be my only explanation... Anyone else experiencing this? And is there anything that can be done about it?
I will have to speak with the rest of admins here and there.
I experienced this issue early this morning in Lemmy.ml during several minutes.
Naive guess is that the self-hosting front end is up, but is spitting out raw errors due to the backend being down
