SSL error Unable to connect to Home Assistant

Configuration Frontend

Hi
All of the sudden I couldn’t connect to Home Assistant. I installed 0.91.1 or 2 and after some days the problem started.

LOG

ssl.SSLError: [SSL: SSLV3_ALERT_CERTIFICATE_UNKNOWN] sslv3 alert certificate unknown (_ssl.c:1056)
2019-04-11 20:40:20 ERROR (MainThread) [homeassistant.core] Error doing job: SSL handshake failed

I have changed to 0.90.1 with out any change. Samba is working and scripts are working. I have connected a screen and keyboard to my RPi and when I do “homeassistant info” it shows another IP than I’m using, 172.30.32.1.

Thanks for any help!

The same here, upgraded to 0.91.3 a day or two ago, woke up this morning, home assistant via duckdns is totally dead. My configs & logs are here…

I have now tested 0.86.1 with no luck. I remember that I updated the add-on DuckDNS. Is it possible to install another version of the DuckDNS at the console?

I have solve (maybe not correct word) it according to @igorovich664 post, link below.

  1. got to https://[local-hassio]:8123 ignore warnings
  2. stop duckDNS addon.
  3. add to your configuration.yaml
http:
  base_url: https://[yourDomain]:[port]
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  1. install and start Let’s Encrypt. I had to set my RPi in DMZ or you can chagne the port forward to 80. Only need to do that when Let’s Encrypt start. Make sure that it work (se the log) then close DMZ or move port forward back to 8123 in your router.
  2. reboot
