NGINX Just Stop Working

Obsolesce

What does error.log say?

Are you running certbot?

NashBrydges

Sorry, running out the door for a client. I'll grab the logs and post the contents this weekend.

I am running certbot for Let's Encrypt.

@NashBrydges Since nginx is running, this should return ok, but you might want to try a nginx -t

Is it up to date?

NashBrydges

@Obsolesce Yes, all packages are up to date.

Here is the only entry in the NGINX error log for the last time NGINX stopped.

2021/01/08 22:34:03 [error] 847#847: *195 access forbidden by rule, client: 195.154.63.222, server: plextrack.jpslconsulting.ca, request: "GET / HTTP/1.1", host: "plextrack.jpslconsulting.ca"

The Let's Encrypt log shows no activity immediately before the outage.

Syslog also shows no errors. It has entries from 3AM to 3:155AM and 9:59PM to 10:02PM on the day of the last incident however the outage occurred between 7:06PM and 10:00PM so the only related entries in this log are at the time the outage was discovered and Ubuntu restarted.

I also ran the NGINX test and all looks good.

certbot.timer failing?

NashBrydges

@black3dynamite I'm not seeing any evidence of this failing in the letsencrypt.log file syslog or nginx logs (both access and error). Would those logs be elsewhere? Obviously I don't want to have to manually renew certs.

black3dynamite

@NashBrydges letsencrypt.log is the only one I'm aware of. Actually are using systemd to renew your certs or cronjob?

NashBrydges

@black3dynamite systemd...

If they weren't it wouldn't even start up.

The error log is where it records HTTP errors, not Nginx software errors.

NashBrydges

@scottalanmiller Well at this point I'm looking at any log that has "error" in the name. Lol

This should show you what there is for Nginx itself....

Oh sorry, use Ubuntu's log. That's RHELs.

Which is useful for in a case I've seen where the service was started by other means, and showed all addresses were already in use.

I thought the modern distros these days were journalctl -f or journalctl|grep blah|less

Just another way to see the same thing.
