Hey Guys ... I am doing a normal Windows Update and i am getting error.
While analysing the application type is ms-update and reason for session end is decrypt-cert-validation.
Appreciate if you guys can support.
What does that no decrypt policy look like? You can't do no decrypt by application right? Thinking you have a destination list, or list of URL's you are triggering the no decrypt on?
Sorry for not clarifying earlier. A no decrypt policy is just a decryption policy with the action set to 'no-decrypt'. We use this for URL's and URL categories.
Did you add those directly to your No decrypt policy, or where is that list getting populated from? - Just asking in reference to where the actual second screenshot resides on your firewall. Thank you for the quick reply!
Its a list we came up with when googling. Here is one just for wsus:
The main issue we face at times is taht the update will fail since the firewall is blocking something. This is mainly due to the backend IP's and DNS changing at a faster rate than the PAN does. Not a knock against PAN, its just the backend MS Updates change and are not all documented.
Thanks a lot for your inputs and suggestions.
I followed your screenshot and added all URL's but i am still not able to update windows.
I am also sharing my Decryption Profile screenshot.
