3028932 - sapcontrol returns NIECONN_REFUSED for a remote instance

The following error message is received when trying to start (or stop) SAP with the command "sapcontrol -nr XX -function StartSystem" (or "StopSystem"; "XX" stands for the Instance number):

FAIL: NIECONN_REFUSED (Connection timed out), NiRawConnect failed in plugin_fopen(), <errordetails xmlns="urn:SAPControl"><errordetails xmlns="urn:SAPControl">Checking Start permission on http://<remote server>:5XX13 failed: NIECONN_REFUSED (Connection timed out), NiRawConnect failed in plugin_fopen()</errordetails></errordetails>

- Notice that the protocol might be https, in which case the port changes to 5XX14 ("...Checking Start permission on https://<remote server>:5XX14 failed...")

Another scenario where the issue can happen is if sapcontrol is used to connect directly to a remote instance, for example:

sapcontrol -host <remote server> -queryuser -nr XX -function <any function>
