SSL/TLS Secure channel - RAF97 - Apr 30, 2020

Hey,

I got an error when I try to download this image...

Code 
Dim wc As System.Net.WebClient = New System.Net.WebClient

       ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3

       System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls

       wc.DownloadFile("https://image-gouda.canadiana.ca/iiif/2/oocihm.lac_reel_t18588%2Fdata%2Fsip%2Fdata%2Ffiles%2F0001.jpg/full/!2560,2560/90/default.jpg?token=eyJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODgyMzA0NzgsImRlcml2YXRpdmVGaWxlcyI6Im9vY2lobS5sYWNfcmVlbF90MTg1ODhcXC9kYXRhXFwvc2lwXFwvZGF0YVxcL2ZpbGVzXFwvLitcXC4oanBnfGpwMnx0aWYpIiwiaXNzIjoiQ0FQIiwiZXhwIjoxNTg4MzE2ODc4fQ.i2BBMCOcmjxpWdsuzrrSzmsD4mfGjMpFjx_LQwWXNbY", "C:\Users\Florent\Pictures\page.jpg")

   End Sub

The request was aborted: Could not create SSL/TLS secure channel.

Works good when I try to download this FB image: https://static.xx.fbcdn.net/rsrc.php/v3/yi/r/OBaVg52wtTZ.png 🙄

Can you help me please?

Cheers!

It was a problem of Visual Studio, the 2010 version doesn't support the protocol tls1.1 and tls1.2.

Thanks.
