Netbox not loading after upgrading nginx

[bthomason2087]

I recently upgraded Nginx from 1.18.x to 1.23.1. I set back up my config file, restarted Nginx, and now Netbox won't load.

Nothing else has changed on my server other than the version of Nginx. I'm running Netbox v3.2.5. The server is Ubuntu 20.04 LTS. The server was originally set up and running at the end of June this year.

All requisite services are running and Nginx syntax and test were both ok/successful.

Not sure what I'm missing here.

I've noticed in the error logs for Nginx, that this appears to be an SSL Handshake failure:

2022/08/10 13:53:17 [info] 1994#1994: *32 SSL_do_handshake() failed (SSL: error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown:SSL alert number 46) while SSL handsha>

Which is giving a Bad Request (400) error when trying to access Netbox. I'm using a self-signed certificate with Netbox.
