core: SSL handshake failed / SSL error errno:1 reason: UNSUPPORTED_PROTOCOL

Home Assistant release with the issue: 0.90.1 / 0.90.1

Last working Home Assistant release (if known): None, new installation (one month, earlier release as well

Operating environment (Hass.io/Docker/Windows/etc.): Hass.io

Component/platform: SSL Handshake fail & SSL Error using DuckDNS/Let’s Encrypt Addon

Description of problem: No connection possible via the https-protocol on several occasions per day. It seems a random problem. When error is happening no https connection via DuckDNS possible. It stops working, than it just works again without any problem solving.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

http:
  base_url: https://my_url.duckdns.org:8123
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem

Same error message in logs: ssl.SSLError: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert certificate unknown (_ssl.c:1056)

My cert was expired, renew certificate - resolved issue

You should edit your local hosts file and add record like this: your internal IP - DNS name In windows path to file is: c:\windows\system32\drivers\etc\hosts Record to add: 192.168.1.101 xxxxx.duckdns.org

Or if your router support host-dns mapping, add mapping to your router configuration

I get this error when connecting to my HA with the internal IP. So configured for https://xxxxxx.duckdns.org/ Can access it correctly from outside my network (via Port Forward 443=>8123). However from inside https://xxxxxx.duckdns.org/ nor https://xxxxxx.duckdns.org:8123/ is working. So I then connected using the ip address. Browsing to https://192.168.x.y:8123/ works, but with browser SSL warning, and then the errors of sl.SSLError: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] came along.

Maybe this helps a bit to solve the problem.

I recently upgraded to the latest and enabled the stream component. My SSL will occasionally stop working (can’t connect) and then sometimes after will crash HA. Curious, anyone else have the new stream component on? May be related.

With 0.91 freshly installed i tried going back to https through letsencrypt in duckdns addon, cause i dislike using http with HA open to internet. I have same error still where https will not let me in at all, not through duckdns adress or https internal ip. I recieve access error, like there is nothing behind. As soon as i ssh in and change configuration.yaml to use http all is working again. Using chrome to access UI, Tasker to update sensors, simple rss widget in android for rss-data. I have some of my config in git if there could be error in my config. the config i have in git is from before https stopped working, 0.90.0 for me. But i will update configuration.yaml so older versions can be used to check what i have changed and so on. Hope someone might have a solution for this.

Hi, I have similar problem, for me nothing through https and duckdns will work. http and duckdns works so i am using http at the moment. Same error message in logs as Rick
