TMG 2010 - No valid certificates were found on the servers in this array

Hi folks,

Help!!!

Basically we have a Web Publishing Rule setup in TMG 2010 and under the Bridging tab I want to change the setting for the Web Server FROM using redirect requests to HTTP port 80, which is what it is currently set to TO use Redirect requests to SSL port on 443.

Now we have a wildcard cert within certificates/personal/certificates on the TMG server but when I chose redirect to SSL port 443 and click select, in the Use a cert to authenticate to the SSL Web Server, my wildcard cert isn't listed in the select cert dialog box.

Just wondering has anyone come across this before and do you know how to sort it!

Any help urgently welcome and appreciated!

Thanks,

Bonemister
