If a remote event consumer (JIRA, Bamboo, FeCru, etc) has a Base URL which does not match the URL used by AppLinks then all remote events are dropped silently (i.e. a mismatch in JIRA will cause Stash not to send remote events to Bamboo, for example).
Consumers publishe via REST the event capabilities they can handle with their corresponding URL. Said URL is created using the application's Base URL. When that URL does not match the AppLinks URL the event cannot be sent and the error is not logged.
