Anyone having issue with SSL (NGINX Home Assistant SSL proxy) (UNIFI)

I setup NGINX Home Assistant SSL proxy but I can’t connect to SSL

I generated my SSL certificate using NGINX Home Assistant SSL proxy

it’s seems ok according to the log

[16:55:01] INFO: Creating ‘snakeoil’ self-signed certificate… Generating a RSA private key …+++++ …+++++ writing new private key to ‘/data/ssl-cert-snakeoil.key’

I have access using and encrypted connection (http://domain:8123 however using HTTS (SSL) I keep having this error “ERR_SSL_PROTOCOL_ERROR”

In UNIFI (My router) I have 8123 forwarded to HA 8123 and 443 to 8123.

I’m not sure how to check the certificates on HA, I instead the plugins file editor but it’s seems that I’m stuck on config/
