Alexa skill configuration not working

Hi I have problem with alexa, I followed Amazon Alexa Smart Home Skill tutorial, but when I use layla.amazon.com (I’m in EU) in Client ID in account link I get an error while linking account “invalid client id or redirect uri” from home assistant. When I change it to pitangui.amazon.com I got an error (while linking account) “Unable to link HomeAssistant with Alexa”. Test discovery in lambda function works fine.
