Error : Nginx Error - Error reloading nginx: reload exited with code 1 signal null

[jordanurbs]

It started when I needed to investigate a bad SSL certificate (NET::ERR_CERT_DATE_INVALID) which came up out of the blue.

Tried a location change on the app (to www.) and it gave me the Nginx Error - Error reloading nginx: reload exited with code 1 signal null... and same thing each time I 'retry location change task'

This is WordPress Developer app btw

I see enough threads on here that offer suggestions for diagnosing or deleting corrupted nginx config files but I can't access the terminal at all, when I open it it's just a blank black screen with the top menu but no way to enter any commands!

Can you run cloudron-support --troubleshoot on the server via SSH?

The nginx configs are on the host system not the app itself (where the webterminal would be launched into)

Restarted the droplet a couple times and now Cloudron is completely down, can't even access the dashboard..

Tried running "nginx -s reload" as root

and got this:

nginx: [emerg] cannot load certificate "/home/yellowtent/platformdata/nginx/cert/_.plvrs.online.cert": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/home/yellowtent/platformdata/nginx/cert/_.plvrs.online.cert','r') error:2006D080:BIO routines:BIO_new_file:no such file)

Alright well I did a ton of forum searching and random things and eventually

/home/yellowtent/box/scripts/recreate-containers 

fixed it, after deleting conf files and what-not.

Cloudron is now back up and the nginx problem is gone for the app.

Cheers everyone.

Just to note here, a server reboot often is not the best idea if some services are still up and running. Nearly everything can be fixed while the server is active and a reboot might just bring down those unnecessarily.
