Cannot get past login-screen - won't accept password on SSL

Close to getting SSL to work on Synology NAS with Docker install using Let’s Encrypt and DuckDNS.

I could use some help on two issues:

  1. HA Login prompt appears (secure), but doesn’t accept the password.
    Same password configuration worked using HTTP

  2. IE doesn’t even return login - chrome does and mobile does… I’ve dumped all the browser data both browsers. IE DOES work to return Synology DSM using same certs and internal IP.

nginx log shows:
2018/04/24 15:03:26 [error] 19482#19482: *65841 upstream prematurely closed connection while reading response header from upstream, client: 10.0.0.1, server: .duckdns.org, request: “GET /api/config HTTP/1.1”, upstream: “http://10.0.0.38:8123/api/config”, host: “.duckdns.org”

Two weeks trying to get SSL working … help getting past this would be great.

Are you using the sample nginx config from HA docs?

Might be nginx configuration error
