Hi @akashdeepAEM,
I think repo is working fine, and what you see is correct behavior due to the fact how Adobe repo has been configured. In general it can not be explored via browser it is readable for maven only. This information can be found under official documentation:
Note: repo.adobe.com is currently not configured to be browsable with a normal browser, but maven use only.

Under above link you will also find details how to configure your settings.xml correctly.
As far as I know, most of the artifacts provided by Adobe can also be found under Maven Central Repository.
