Thanks for reporting this. As it seems the rest of your website pages works so there may be an issue with the URL of the linked page. Its unclear if another service is integrated with handling of the page (ex. Cloud Storage) so please specify if any are and provide a snapshot of the Stackdriver logging of the Not Found error triggered when trying to access the page if applicable. To locate that please go to Cloud Console > Logging > Select GAE Application, service id etc and check the HTTPs code of the errors as well as the error message as that should provide more details on the cause of the issue. Its unclear if "instances" refers to services/version of an App Engine applicable or resource instances but the number of neither matter when dealing with errors as if the code is similar (errors are present in any of the services/version) the issue could occur and if the resource usage is low then the number of instances does not likely reflect on the cause of the issue.
