Well, here is the reason that you cannot restore

==================
Object name : **********:/96b8a312-65c1-403f-b036-09380f62c55e/Database1
Protection : Protected for 5 days (Expired)
Catalog retention : Same as data protection.
=====================
which is one of the things that I mentioned as a possibility for causing this problem:
"Check the backup to be sure that it is still protected"
My guess is that the media protection expired, the Catalog was deleted, and the media 'FilePool_298' was written over. You can check this by running
omnimm -list_media FilePool_298 -detail
