@tim_g Np. Thanks

I prefer to have each server block for each domain/subdomain in it's own config file.

Like this, this is a good example of what I meant...

@jaredbusch Understood. Thanks. I bet multiple configs makes it easier organizationally and also when troubleshooting so you have less to go through.

That is my preference, yes.

Not really. Just everything is broken out.

So I ran into this

but the nginx documentation here points to this: https://nginx.org/en/docs/http/server_names.html

Is there an error here I'm not seeing? I mean, there must be. Each time I make a change I systemctl reload nginx

Actually I think I figured it out. made a mistake with the .conf files

@wirestyle22 Share your resolution if you will. I was trying to install nginx on a server with wiki.js the other day and was running into the same error.

I never run certbot with one of the specific switches like --nginx or --apache. Ever.

Fuck letting some 3rd party script edit my configuration files.

I run in standalone mode and edit the conf files myself.

I also include multiple SAN on my certs, so the same SSL file is in multiple conf files.

But doesn’t ‘certonly’ keeps it from editing the files?

LOL - JB doesn't trust scripts from LE or whomever made them, but he for some reason trusts other people's scripts.... LOL

I thought he said something about magic scripts that he doesn’t like?

Scripts that install software is different than scripts that change your configuration files.

I run the certbot scripts, no problem. Just not in a way that lets them fuck up my configuration.
