Title: NodeJS 503 error after app restart
Post by: josephgodwinke on May 20, 2022, 12:54:28 PM
I restarted NodeJS app here:
Code: [Select]
module=mod_nodejs
Nginx service runs well. No nginx errors

But still I have 503 service unavailable error

I restarted server but no luck.

Following the directions here - https://wiki.centos-webpanel.com/webserver-errors does not help either.

Code: [Select]
