1 pointNot sure what Microsoft did to cause this in the Dec security update as well but the missing asp.net session cookie may be related to the upcoming changes to samesite cookie https://support.microsoft.com/en-au/help/4522904/potential-disruption-to-customer-websites-in-latest-chrome https://devblogs.microsoft.com/aspnet/upcoming-samesite-cookie-changes-in-asp-net-and-asp-net-core/
1 pointThanks for the quick reply. I will take a closer look at it and test it and get back to you.
1 pointThanks, and I can see the issue now - I just tested this also: You have your Invoke-RestMethod inside the json object - although you probably have moved this out by now And the GenericField1 and Description fields do not have a double quote before the single quote for your PowerShell variables i.e. should be "GenericField1":"'+$ServerName+'", instead of "GenericField1":'+$ServerName+'", I know it's hard to see in this forum, but cut and paste the text above and you will see what I mean.
