custom url filter action continue and ssl decryption

i have configured few custom url and action is set to continue.

for some https websites i get response page and when i click on continue it works fine.

 

for some https websites chrome shows error connection reset.

PCaps on PA does not show any drops.

traffic logs show session end reason threat and CLI shows discard.

 

below is custom url where action is continue which do not work

*.wcb.ab.ca/

wcb.ab.ca/

 

Above url works fine when ssl decryption is enabled.

Need to know response page with action as continue works for some https websites and not for others why?

Re: custom url filter action continue and ssl decryption

we open the tac case and issue was fixed via this

 

set deviceconfig setting ssl-decrypt url-proxy yes

 

As per Tac 

This enable the Palo Alto Networks device's ability to inject URL filtering response pages within an HTTPS session.

 

IF some here explain in more detail that will be much appreciated

Re: custom url filter action continue and ssl decryption

Hello,

I suspect that this is getting blocked on a mismatched or not allowed Application. However since this is a medical site. I would suggest that you do not decrypt it, due to compliance and privacy issues. Here is a list of catagories we do not decrypt for this reason:

 

Military

Health and Medicine

Financial Services

Government

Hello,

Check the Security policy to see which URL filter it is using then check the URL filter to see which catagories are blocked.

Hmm, that is strange, maybe a tac case?

 

Custom catagories are processed prior to the Pre-Defined ones.
