I'm trying to enable TLS 1.2 for outgoing connections from a classic ASP site running on IIS. I have tried adding the registry settings outlined in the questions below but this hasn't helped.
Check if Windows Server 2008R2 can use TLS 1.2 How do I disable TLS 1.0 without breaking my IIS/ASP.NET websites?
The app pool for this site has Enable 32-bit applications set to True. I noticed that if I create a new site and set Enable 32-bit applications to False then outbound traffic from the test site uses TLS 1.2.
