Occasional connection attempt failed error

    Question

  • Every now and then our application hosted on Azure Web Sites (standard) encounters the error: 

    "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond [IP]:80"

    It occurs when attempting to consume an external web service over HTTP. This issue is not reproducible on our local environments nor did it occur with our previous shared hosting provider. On Azure, the same web service call can result in this error or will return a response successfully. There doesn't appear to be any pattern as to why the same call would work one time but not another.

    Any insight as to why the error only occurs sporadically is greatly appreciated.
