We also have this problem... We read on this Microsoft Q&A link below, that the paramater enable-udp-fragment-reordering is only possible to enable on a new subscription without any resources deployed on it: https://learn.microsoft.com/en-us/answers...
Thank you so much, it would be very helpful if you could share the reply to the Cisco ticket when possible. In the meantime we'll try the workaround. Thanks again
We have this problem too.Only solutin for now is the one suggested from you:deleting the cisco anyconnect profile and cleaning the SSL cache.Anyone with a fix for this?
