Hi Nikos, This seems to be a new question: how to detach mapping of your custom domain to your service. You did not mention this purpose till now. For a new question, it is better to open a new thread, but not in Groups. This forum meant for general discussion on the platform and its services, not technical matters. If you think you have noticed an issue with Google Cloud Platform, the place to open a new issue were the Public Issue Tracker <https://issuetracker.google.com/120558889>. This is not the case, as you simply ask for advice. In your case, forums such as stackoverflow would be appropriate, where experienced programmers are ready to provide expert advice.
To detach the mapping of your custom domain to your service, you can simply follow the advice provided in the "Deleting a custom domain" sub-chapter <https://cloud.google.com/endpoints/docs/openapi/dev-portal-setup-custom-domain#deleting_a_custom_domain> of the "Setting up a custom domain" document. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
