I fixed this 30 minutes after I posted this. So for anyone else that has this issue, It
turns out that the cert wan't getting imported after running the command "keytool
-import -alias ovirt -keystore ./cacerts -file <3rdpartycert>.cer" manually, as
"update-ca-trust" did not add it automatically. Also, the default password for
the keystore is "changeit", and I put the keystore password in the
"99-custom-truststore.conf" file, not the "" entry like the article
says.
