    Great, I installed the fiddler update. Now I can no longer decrypt https client traffic while debugging.... 

    "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel"

     

     I had the fiddler cert trusted before and didn't get a prompt to trust it when enabling https decryption.

     

    So I uninstalled Fiddler and removed the certs.  Then reinstalled and I get the prompt but my apps are still faiing....

    Resolved this with a post Eric had already made here...

    http://www.telerik.com/forums/firefox-36-0-breaks-fiddler-https-decryption#lqgIHIvos0qnERndygnFuA 

     

    Turned decrypt https off and had Fiddler remove the certs.  Then restarted and reenabled https decryption. Worked

    I tried the advice at the link provided for my situation and it did not work.

    I have Windows 10 and Kaspersky which does not like the certificates/routing provided by Fiddler2.

    This appears as a new manifestation of an old problem where no links are accessible through Firefox, Chrome, Edge/IE when Fiddler2 is operating.  Closing Fiddler2 allows browsers to work.

    What is the current solution for this problem?

    Thank you,

    Jeff
