Using a desktop web browser…
It doesn’t seem like a timeout, it is always fast to respond with the error and also fast on successful loading pages. It seems to me there is some kind of resource/parameter starvation in nginx or the nginx bridges to the NodeJS app…
I’m also seeing problems with static content loading, images and css files not loading and getting a mangled half-generated page or missing icons for upvote/downvote that I have to refresh the browser with. This happens at least 1 in 8 refreshes of the page.
I’ve spent over 60 hours in the past 11 or 12 days on this problem, and it’s been brushed under the rug. There are MAJOR problems being logged on that server, and the server logs are not being shared.
