Arcgis 101 Error code 499 Token required.

Discussion created by vadivelan.gis on Jul 24, 2013
Hi,  we faced an issue in the arcgis server 101/html5/js api, when apps try to request the ESRI map service, in the client slide we go this error "token required".

We found that the map services security are changed from public to private.  After making it as public, the apps started to work fine. 

Right now, we are not able to find the root cause of this change, who/how it got changed.  We had MS patch installation happenned in this machine two days, but the same patch has been applied in DEV environment, the DEV has not have any issue.

Do you ever faced this kind of weird issue ? any idea about this and how to prevent this ?
