Joomla 3.2 Two Factor Authentication Problem

Has anyone else experienced a problem getting two factor authentication to work on a Joomla 3.2 install on Dreamhost?

I’ve had no issues on other hosts, but here, any attempt to activate it seems to be ignored.

If anyone has suggestions on what to try, please let me know.

I get the key, create an account in my code generating client, and enter the current code in the user page. Hit save, and nothing happens. It just reverts to “Disable Two Factor Authentication” (after a save, it should stay on google authentication and generate emergency codes, but not here.)
