I know leet should probably be reporting this but I'm having an issue with 502 bad gateway. Also all of the leet forums (including the main forum) are now not working due to this.
502 bad gateway is the error that nginx returns when NodeBB isn't running. Try running NodeBB will ./nodebb slog or ./nodebb dev and look for errors. Odds are that it is encountering an error and dying.
Your forum may work, but has no security, anyone can login and delete/steal the database. You need to setup your redis so that it has a password, and that it restricts access to localhost.
Or leave it as a reminder to anyone else that runs into similar issues with leet forums. Both work. All the informations in this topic. Or to summarise:
We don't support it.
We can't help.
