Hi 

I am currently in a highly restricted network. When I ran the EPi Find Indexing job on my local machine, I got the following errors 

EPiServer.Find.ServiceException: The underlying connection was closed: The connection was closed unexpectedly. ---> System.Net.WebException: The underlying connection was closed: The connection was closed unexpectedly.
   at System.Net.HttpWebRequest.GetResponse()
   at EPiServer.Find.Connection.JsonRequest.GetResponse()
   at EPiServer.Find.Api.Command.GetResponse[TResult](IJsonRequest request)
   --- End of inner exception stack trace ---

   at EPiServer.Find.Cms.ContentIndexer.<>c__DisplayClass19.b__e(IEnumerable`1 currentBatch, ParallelLoopState loopstate)

Could someone suggest me what firewall rule change do I have to request IT department to add in order to make it working?

Thanks
