Forefront TMG was unable to establish an SSL connection

Hello All,

I have a TMG server connects with the Sharepoint web page.

Once in a while I am getting page can not be displayed error to the https URL were as the URL without TMG is working fine. So I am sure the error is only with TMG.

Error Message:

Forefront TMG was unable to establish an SSL connection with 10.175.221.26. The
handle specified is invalid

Please let me know if any one has Idea,

Thanks

Karthi
