Esri helped my organization set up the proxy server for the ArcGIS location service a while back.
We recently created an application that calls a REST service from the proxy and gets a JSON response. Once in a while we get an HTML response with an error message instead of a JSON response, which causes our application to fail. We thought that it might have to do with the file size of 10,000 records, but we found that it failed intermittently with few records also.
We had our network team check our communication between hosts, and they did not find any problems.
Can you please help us troubleshoot this problem?
