Done.

Run the ISA firewall BPA to make sure your certificates are in order.

Problems:

1) The certificate used by the server specified in a Web publishing
rule cannot be validated

To correct this warning, do one or both of the following
Add an access rule that allows HTTPS traffic from the Local Host
network to the network where the Web server resides.

Check your network layout and connections.

2) Same error

3) Enabled PMTUDiscovery Reg key to 1

Make sure you're delegating basic authentication

Done. (Under the Users tab of this policy).

Make sure the ISA firewall is a domain member

It was and is.

Thanks, Tom.
