It looks like the MFA OnPrem agent doesn't support RADIUS passwords longer than 16 characters. We tested with different password lengths and the integration breaks with any password longer than 16 characters.

Thank you for reaching out to Okta Support, my name is Vlad and I will be handling this case.

I've test it out and I am able to use a password with more than 16 characters.
