Error linking bitbucket on cloud with jira server

I generate de OAUTH like here is explained: https://confluence.atlassian.com/bitbucket/connect-bitbucket-cloud-to-jira-server-applications-814208991.html

I added the Keys correctly but I don't see any repositories and when click on Configurate automatic access I can see this warm in the log:
