I have my HA running on duckdns and able to integrate google assistant. Now I am trying in Alexa, when I link the account in the app it says " unable to link home assistant with alexa".
I read on the forum about port forwarding, I am already working with port 8123. So dont know what to edit.
I did the test in Lambda function and it worked.
in HA I have this error:
Login attempt or request with invalid authentication from ec2-54-74-32-16.eu-west-1.compute.amazonaws.com (54.74.32.16). See the log for details.
