Troubleshooting steps.

I want to secure the internal URL of HA.

• I have two HA instances, both running the latest version of HA and both run Nginx Proxy Manager.
• Both HA instances have a Lets Encrypt cert for the public-facing FQDN.
• The process described above worked perfectly for the first instance.

I have checked the logs for Nginx Proxy Manager, but there is no mention of the failed certificate upload and I cannot find any information on how to increase logging verbosity.

The cert/key does not have a passphrase and I have checked the cert/key match.

I've tried everything I can think of. The fact the process worked for one HA instance is really foxing me. If anyone has any suggestions, I'd be grateful if you could share them.
