Hi Ashish,
I have just spent some time discussing this issue with the Adobe support team.
They have sent me a list of sites:
ccmdls.adobe.com
ims-na1.adobelogin.com
ims-prod06.adobelogin.com
na1r.services.adobe.com
prod-rel-ffc-ccm.oobesaas.adobe.com
prod-rel-ffc.oobesaas.adobe.com
lm.licenses.adobe.com
ccmdl.adobe.com
swupmf.adobe.com
swupdl.adobe.com
Please can you assets that this will help or not.
Regards,
Ayush
