YouTrack GitHub integration fails with 401 Unauthorized using valid token

I try to set up docker container with jetbrains youtrack and github intergration:

repository url i paste: myuser/myrepo

since the full url returns:

Invalid repository path format: https://github.com/myuser/myrepo

and to Auth i generate a token- classic github token with full access:

ghp_123456

The token: -is valid -have full control over everything -covers all scopes and repos

and i get:

org.eclipse.egit.github.core.client.RequestException: Unauthorized (401)

I use also ngrok.

In the fields i have a valid data:
-url with userName/repo
-token generated iwth generate token option
-url as grok url i can access from browser 

Why the url simply doesnt work? Why i get 401?
