    Yes; configuration settings for the web server involving improving performance. Those settings have been changed back to the previous, non-issue ones. So this should not occur at this time, or again.

      Is this a mistake that’s easy to do for an inexperienced instance admin or just a consequence of too much fiddling and shouldn’t be an issue for other instances?

        Was a result of too much fiddling. Attempting to gain even better performance from a bottleneck issue due to recent user influx. It was not an error in the Lemmy instance or Lemmy-UI but rather the web server front-end misconfiguration.

          Thanks for working through these issues and improving performance of the website! Very appreciated. I’ve been tempted recently to create my own Lemmy instance, was this a problem with an nginx configuration option? How much does Beehaw deviate from a standard Lemmy deployment?

          Feel free to answer vaguely if you don’t feel comfortable with giving away the details : )

            was this a problem with an nginx configuration option?

            Basically, this was proxy_cache_key being configured incorrectly. If you don’t use the proxy_cache you should be fine.

            The only thing we changed from the norm is ulimits and some nginx settings. If we figure out what works well, we’ll probably create a post about how to host lemmy. If you stick to the defaults, you’ll be mostly fine if your instance isn’t as big as Beehaw’s.
