I have started configuring my EPORTAL system and in the process of connection Testing to my ECC Development server I get the below error in the ITS Connection Test Details.
An HTTP/S connection to http://sapeccdev.zentagroup.com:8000/sap/bc/gui/sap/its/webgui?sap-client=100 was not obtained successfully; this might be due to a closed port on the Firewall.
When I login at OS level in the EPORTAL SYSTEM and directly put the URL of ECC Development system it works fine in the WEB GUI. Also the web GUI works from any other PC in our organization by direct use of URL.
I would like to know when I test this from EPORTAL is this due to some closed port as this working by direct use of URL and what might be the possible cause of error.
