We tried upgrading our EP server to SP13 from the previous SP09 patch level, using JSPM.
After deploying some packages, when it reached JEECORE package, it got failed. But JSPM did not give any error message.
It tried to restart the server. But after restart, the server is not connecting. In the MMC, all the nodes are green showing successful restart. But when I try to access the portal, it is showing an error message as given below:
503 Service Unavailable

I checked the trace files.
I saw the following error message
Encomi: failed to connect to sapXXX/3251/Connection refused: connect)#
Can anyone help us out?
