After SDP server migration Notification $Requestlink shows old hyperlink

Hello to all,

we have migrated SDP server to a new server following your FAQ instructions. Everything is working fine except $Requestlink hyperlink in notifications. Problem is that notification shows url correctly but hyperlink is different and use old server url

Example:

Link displayed on notification: http://newserver:port/WorkOrder.do?woMode=viewWO&woID=83
Hyperlink on notification: http://oldserver:port/http:/newserver:port/WorkOrder.do?woMode=viewWO&woID=83

We have change url alias on Self Service Portal Settings and restarted server but it's not working.

Thanks in advance
