I've been sporadically encountering errors with my REST API calls to backend services. The error response includes:
errordetail: Unknown host: Read timed out
filecontent: Connection Failure
statuscode: Connection Failure. Status code unavailable.
In the past month, the issue has occurred today, July 4, July 2, June 29, June 12. As far as I can tell, nothing has changed on my end. This failure was such a concern on/around April 22nd that I setup behavior to automatically retry the call when it fails. The retry often succeeds within three attempts. This issue by no means occurs on every call - most work fine.
The specific operation that is failing is GET / Users / with a MasterKey and Username filter. I would need to investigate further to determine if other operations are occasionally failing as well.
