It seems the second server returns "Could not create SSL/TLS secure channel.".
Tha solution here https://wyday.com/forum/t/3882/error-downloading-could-not-create-ssltls-secure-channel/#post-22523 is:
"Use .NET 4.0 version of wyUpdate, and fix your registry settings."
Where do I find ".NET 4.0 version of wyUpdate"?
