ADFS 2.0 Event Error 422

My ADFS Proxy server lost it's trust from our Federation service when we were having issues with our firewall.

Now when I go to reestablish that trust relation ship it fails.  We are using the same certificate and all that information in the first few screens when trying to reconfigure in the Web Application Proxy Configuration Wizard.  When we hit the Configure button we get an error:

AD FS proxy could not be configured.

An error occurred when attempting to establish a trust relationship with the federation service. Error: Unauthorized. Verify that the service account has administrative access on the target Federation Server.

The Event Viewer for AD FS shows an error ID of 393.
General Information below
====================================================================================
The federation server proxy could not establish a trust with the Federation Service.

Additional Data
Exception details:
The remote server returned an error: (401) Unauthorized.

User Action
Ensure that the credentials being used to establish a trust between the federation server proxy and the Federation Service are valid and that the Federation Service can be reached.
===============================================================================================

The user is the same user we have been using all along, the password is still valid and that user is established as an administrator on the main ADFS server.  All the information is identical to what WAS working earlier yesterday prior to the problem.  Any ideas?  Thank you!!
