Cannot conduct archive search via a particular EV URL on IE same URL works on google
We have been able to configure a bunch of URLs from Kv 1-19 allow EV archive search via IE and other browsers with the exception of just 2 URLs with the same FQDN that are still not working on IE. Once a search.aspx is conducted on these URLS on IE it tells you the search cannot be completed please contact your vault administrator, after a while you are presented with admin login screen.
Inspecting internet properties > security > local intranet > shows uknown zone (mixed content). The URL for the above is same as the url of the other 17 working urls kv(1-19.)com.net so it is baffling why this is happening to just these particular two URLs. Could there be something wrong with those 2 urls on the EV side of things?
NB: Resetting IE on client actually gets the Archive Search working again for both URLs on IE but that is not a solution.
I heard there is a registry entry that could be implemented in policies or via registry to get this working.
The behaviour and the solution recommended in this thread https://vox.veritas.com/t5/Enterprise-Vault/EV-11-0-1-Search-Session-Expired-Problem/m-p/726159#M100283 looks similar but i will not place all bets on that . Could use some help.
