SSL Errors wrong version number?

You can access it locally without https and externally with https using your DDNS. That is the magic of NGINX. Have you port forwarded 443 to 443 Hassio?

I have got 443 forwarded in the router.

Additionally, I tried clearing the browser cache and got this error in firefox:
Error code: SSL_ERROR_RX_RECORD_TOO_LONG

And just to confirm - I can now access locally, but I cannot access it externally using https://

Have you tried to recreate the certificates? Try restarting or even reinstalling DuckDns addon.

You also need to forward 80 to 80 Hassio for certificate renewal.

Here works just fine.

I have time to have another blast at getting nginx going today. I’m still running into problems though in that I cannot now access hassio remotely (https).

What I have done:
Removed these lines from my configuration.yaml:
# ssl_certificate: /ssl/fullchain.pem
# ssl_key: /ssl/privkey.pem

Reinstalled duckdns, which has regenned my ssl certs
changed my port forwarding to the following:

installed nginx and configured as:
{
“domain”: “yourddns.duckdns.org”,
“certfile”: “fullchain.pem”,
“keyfile”: “privkey.pem”,
“hsts”: “max-age=31536000; includeSubDomains”,
“customize”: {
“active”: false,
“default”: “nginx_proxy_default*.conf”,
“servers”: “nginx_proxy/*.conf”
}
}
tooka ages to start - but eventually did.

when I try to access hass using my external IP (https://myhassio.duckdns.org) I get the following:
“Unable to connect to Home Assistant. Retry”

also - my log is filled with this:

Anyone have any ideas?

I have the same issue here, ended up going back to original config without nginx…

Has this been resolved?
