Recently, in one scenario, I was being asked on my email that somebody was facing network error on their ODATA call:

Everything seemed find with ODATA request and I was not able to find the root cause of where the problem was coming from.

All the URL’s and request parameters were correctly set. Still, there was network error occurring.

The resolution was quiet simple:

· URL was working with IP address instead of server name, so first thing was to get it corrected

· Second thing was to add CRM to trusted sites:

In Internet Explorer, navigate to Tools� Internet Options. A window pops up containing multiple tabs. Under the Security Tab, click Trusted sites and then the Sites button.

2. In the pop-up window type the trusted site names (https://*.crm.dynamics.com and https://*.live.com), one at a time, and click �Add.

This resolved the error, Hope it helps and Happy CRMing!
