Thanks Srivatsava for your inputs. We had configured Cloud tenant to integrate with SAP JAM successfully. But yet we were getting issue because of not supporting browser.
I was getting the unauthorized issue was due to wrong Internet Explorer version. This integration is working fine with IE 9. SAP has also recommended to use IE 10.
Regarding IE9, with the latest release of SAP solution in which they have rolled out an html5 based platform, due to the poor support of HTML5, IE8 does no longer make sense.
IE 11 is pretty recent - Microsoft released it last year, and by now it might not be fully compliant with SAP solution. So in case of IE11 issues so far, SAP has troubleshoot as far as possible, but may recommend a ‘safe fall-back’ to IE 9 or 10.
Also note that this is also not working on Mozilla and Chrome.
Thanks & Regards,
