Oauth2 not configured correctly


I want to deploy an own alexa skill to make it work with my openhab cloud instance but it seems like oauth2 is not configured correctly. At least I think so because of this post.
I used this links https://openhab.mydomain.com/oauth2/authorize and https://openhab.mydomain.com/oauth2/token
Using the first one I can login with my credentials. Using the second one I get the response Cannot GET /oauth2/token
How is oauth configured?

Best regards

I did everything from scratch but I didn’t do anything different and no it works. :man_shrugging:t3:
