I have been running an ArcGIS Server 10.3 on Amazon Web for over six months and in the last week I have noticed a change when I try to publish a map service. Because of security in our organization, I create a service definition file locally that links to an Oracle enterprise and then I copy the .sd file to the map server in the cloud and publish service through ArcGIS Server Manager. I have successfully ran through this process many times but last week when I tried to publish a new service, in the first window of the "Publish Service" process where I choose the service definition file, I now see a jsontoken reference at the bottom of the pop up window. When I do choose a file that is on the map server directory and select NEXT, I now see a notice that says "Please wait while the service definition is copied to your server..." and then it thinks for a while until manager times out. I have not changed my publishing process but I have never encountered this information or behavior until the past week. I know Windows OS patches have been installed but I wouldn't anticipate the operating system interfering with the ESRI Server Manager although I could be wrong. Has anybody else experienced this issue and have you found a way to work around it?
