The issue may stem from GEO Jobe’s web server acting as a proxy to data server. This is required by current Esri technology so a proxy can be leveraged to append a token to the end of the request. The appended token is locked to a specific IP address (GEO Jobe’s web server). Sometimes, the use of a proxy can be a “red flag” to an IT professional that perhaps someone is trying to circumvent a firewall rule. By default many local governments and larger corporations may block web requests that leverage proxies. In this case, an exception rule would
need to be setup for the GEO Jobe server that handles the Property Search Application. This would explain why it appears to work fine for GEO Jobe and other public users, and networks, but consistently has issues for others.
