I tried to publish a simple small shapefile to the hosting server from Portal. I am using "Add from My Computer"
I received the error 999999, Error executing tool. Publish Portal Service Job ID:j1a2b......, Error executing function, Bad syntax in request (status code 400). Failed to execute (Publish Portal Service). The source of the error is: System/Publishing Tool. GPServer.
I am able to user arcmap and publish service to the hosting server as feature layer. Therefore, the hosting server and the datastore appears function properly.
I really don't know where to look for the solution. Wonder any one had similar problem for the Portal 10.6.1.
