Custom property history summary in 2023 R2 P01

I suggest contacting support as this should not have changed, 

Hi Benoit!

This might sound far-fetched, but could you try and repeat your test, excluding the script or any use of System.DateTime namespace.

I have seen several issues in recent versions where script referencing to this just don't execute. (it has been reported).

What I'm aiming for is if you could repeat your test with hardcoded references or set the DateJ to DateJ7 manually, just for the sake of troubleshooting. Does this make any difference?

But as John suggest, the support is the way to go, but if you have the possibility, report back your findings here.

Hello,

I apologize for the delayed response. It was a certificate issue.

By retrieving the certificate generated by our Historian server and then importing it onto our RDS machines, the connection to the server is established, and the custom properties "History Summary" are functioning again.

Now we need to understand why our machines were unable to automatically retrieve the certificate.

Thanks for your help !
