    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.
