Nope. Still can't serve. It's now stubbornly serving a completely different site if I use "try_files $uri @PROXY." If I use "try_files $uri /$uri =404;", it gripes b/c there is no index file & it won't do a directory listing. Automatic installation script skipped files. This is non-trivial. Having to search for solutions all day was awful. You want us to host, but online help is poor.
#mastodon #installation from #source is difficult with INCORRECT DOCUMENTATION!
I'm not a dev or sysadmin, I can't give help with manual installation.
All I can suggest is asking about this in the github either as an issue or in the discussion section.
