Hi all,
I just ran into the exact same issue, even though I was pretty sure the password was correct (unless my PC's copy-and-paste function was broken). After some testing, seemed that the .pfx (renamed to .p12) was exported from a Windows machine using AES256-SHA256 to encrypt the export-password. Re-exporting the certificate with a 3DES-SHA1 encryption of the export-password did wonders.
Just adding my two cents here. If it saves anybody some time, it was worth the while.
