NGINX 404 Error

[halcyon shell]

Hello all,

I'm looking for advice on a 404 error that's blocking progress on my Tesla integration. I need to be able to access the public key. My DNS and NGINX is configured. When attempting to access the file, I get a 404.

Via this link, in the "Move the keys into the proper locations" section, you'll see where they're stored.

TL;DR:
/share/tesla/.well-known/appspecific/com.tesla.3p.public-key.pem

It should be accessible via this URL

https://mydomain.duckdns.org/.well-known/appspecific/com.tesla.3p.public-key.pem

Any advice on this will be greatly appreciated.

I'm facing the same issue as well following the same guide. Does your setup look the same as mine?

[halcyon shell]

For the most part. I updated the trusted_proxies to my internal subnet. My Customized is set to false. Perms, location, and just about everything else look spot on.

Try setting the customize.active to true. In his document at the Configure NGINX section, he mentions you need to set that to true for the nginx to actually pick up the changes

[halcyon shell]

Strange, in the GUI it's set to true but in the yaml it says false. Changed it anyways. Same 404.

I did a "Check Configuration" and am getting these errors:

Integration error: real_ip_from - Integration 'real_ip_from' not found.
Integration error: certfile - Integration 'certfile' not found.
Integration error: domain - Integration 'domain' not found.
Integration error: customize - Integration 'customize' not found.
Integration error: keyfile - Integration 'keyfile' not found.
Integration error: hsts - Integration 'hsts' not found.

Not sure if it's a clue or a distraction.

@halcyon shell I got it working! This is what I did.

• Updated my port forward on my router for 443 => 443 based on this thread
• nginx_proxy docs say to remove ssl_certificate & ssl_key so I did that as well
