Could not create SSL/TLS secure channel

Hi , 

I just upgraded to Power BI Desktop RS to latest version May 2024 and a web data soruce is now failing with 

DataMashup.Trace Information: 24579 : {"Start":"2024-06-06T13:46:38.8821650Z","Action":"BackgroundThread/RollingTraceWriter/Flush","ProductVersion":"2.129.255.0 (24.05)","ActivityId":"00000000-0000-0000-0000-000000000000","Process":"Microsoft.Mashup.Container.NetFX45","Pid":12800,"Tid":4,"Duration":"00:00:00.0000800"}

It seems that the new version of Power BI Desktop uses an old TLS version that it's not supported by our network policy.

Where would Power BI Desktop choose what version of TLS to use?

Thanks
