[Solved] Certificate mismatch

Help
1

For some reason, this domain is picking up the certificate for a different domain (which is the preceding one before it in the nginx conf sites-enabled directory). Where should I look to fix this?

My domain is:
api.usermanagement.tgmgroup.net
I ran this command:
certbot-auto --nginx -d api.usermanagement.tgmgroup.net
It produced this output:
Seemed to work
My web server is (include version):
nginx 1.4.6
The operating system my web server runs on is (include version):
ubuntu 14.04
My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):
Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
No

Nginx conf file is here - https://pastebin.com/cAkNWAjf

The pasted nginx configuration looks seriously broken to me.
Six server blocks for one domain name, four of them completely equal, no listen 443 ssl statement…

Thanks - I noticed the 443 and am putting it in now (I’m more used to Apache). I deleted the other replica blocks (I think certbot-auto keeps putting them in at the end).

I would check if nginx actually loads this file on startup.

It does. It has been running happily for 3 months (until the cert didn’t update).

I’ve added the listen 443 and ssl certificates in the server block and it’s working. Note to self - if certificate breaks, somehow other certificate gets served up.
