Important note about SSL VPN compatibility for 20.0 MR1 with EoL SFOS versions and UTM9 OS. Learn more in the release notes.
Using TLS decryption and vendor Docusign suddenly causes issues with our XG firewall on 19.5.3.
Happens also on other browsers and OS. Here Safari in MacOS.
it works using classic proxy as described here:

I wonder why that suddenly happens and what will happen with such sites when Sophos turns that "classic proxy" off some day?
update: admin.docusign.com was no longer working even in classic proxy.
it was required to add an additional exclusion for https decryption in classic web proxy for admin.docusign.com

LHerzog,
Thanks for posting this. We had experienced the exact same issue earlier today and also had to bypass decryption for this site. Is it possible the sites are dropping the older, less secure encryption protocols and cipher suites and the XG has trouble decrypting the protocols in use? Below is from the apps.docusign.com site.
