Yikes - 502 Bad Gateway Nginx DigitalOcean

Michael Pfaff

Suddenly getting a 502 Bad Gateway at my NodeBB install: community.nerdlouisville.org

Main site works fine: nerdlouisville.org

Any advice?

Is NodeBB running still? The process might have crashed.

Not sure how to tell.

Use sudo as needed depending on how you are logged in.

cd /your/nodebb/dir
# look at the log
./nodebb log
# or just restart it
./nodebb restart

Log contains: error: TypeError: Request path contains unescaped characters

at new ClientRequest (_http_client.js:53:11)

Restarting: NodeBB could not be restarted, as a running instance could not be found.

I did just recently add some custom HTML (from this thread: https://community.nodebb.org/topic/9917/javascript-html-widget/8) to the header. Could that have been an issue?

Run ./nodebb start && ./nodebb log and see if it crashes again.

That reloaded the site, but when I try to register a user, I get:

Registration Error

<html> <head><title>502 Bad Gateway</title></head> <body bgcolor="white"> <center><h1>502 Bad Gateway</h1></center> <hr><center>nginx</center> </body> </html>

Which I saw right before the full Bad Gateway.

Nothing new on the logs when that happens?

less +G ./nodebb/logs/output.log

Seems like when I disable the No Spam plugin I don't get the error.

Will need logs to debug

Will try to go to this soon! Sorry. Had a busy weekend.
