Access via DuckDNS stopped working - SOLVED

Installation Home Assistant OS
1

So here is the strange situation.

Two days ago, I was able to access Home Assistant fine, both locally using 192.168.x.x or externally using xxx.duckdns.org. I updated to 0.66 and then yesterday evening noticed that I was no longer to access via DuckDNS either when inside or outside my local network. Tried downgrading to 0.65.6, but same problem. I do not believe I have changed anything and this setup has been working for the last 3 months.

My configuration for Duckdns is below

{
  "lets_encrypt": {
    "accept_terms": true,
    "certfile": "/ssl/fullchain.pem",
    "keyfile": "/ssl/privkey.pem"
  },
  "token": "abc..............xyz",
  "domains": [
    "###.duckdns.org"
  ],
  "seconds": 300
}

and the corresponding extract in my configuration.yaml file is

http:
  base_url: !secret base_url
  # Uncomment this to add a password (recommended!)
  api_password: !secret api_password
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem

When I attempt to log in, I just get this…

Any ideas what might have changed? Or have I overlooked something obvious?

Check in your duckdns account that the address match your home public ip.
Also check in log for any error related to duckdns

Just checked the IP address. It seems to be OK. Furthermore, I see no errors in the log related to DuckDns.

Probably completely unrelated, but I have a strange log entry for my Nest. Not sure it is not related ,but I’ll add it just in case.

Solved.

It seems there was some issue with cookies stored on my web browser. Once I cleared the history, I could access via xxx.duckdns.org. Apologies for the hysteria and thanks for the help.

Same issue after update to 0.77.3 with hassbian, I just removed all cookies and It worked again. Unfortunately you have to erase cookies from all browsers your using HA with.

Great that worked for me also. Been trying to sort this for a couple of weeks, wasted so much time checking out the configuration. Anyway, sorted now. Thank you @Swiss
