@sachin_bhide The change you notice appears to be the result of a system configuration change made some time ago and announced at Removing default Indexes for collections under /public/html. Please contact the collection maintainer regarding restoring access to the content. Contact information for them can be found at the end of the page About – Guruguhaorg.
