  • User-1720211928 posted

    I have enabled strict TLS 1.2 in all my windows server 2012 R2's web servers(IIS) under load balancer by enabling TLS 1.2 and disabling SSL 2.0, SSL 3.0, TLS 1.0 and TLS 1.1 explicitly in the registry. Also I have enabled use strong crypto registry key. How can I check whether the outgoing calls from my server are actually TLS 1.2 compliant?

    Hi mgurjar5,

    According to your description, if you want to caputre the outbound request which send from your server, I suggest you could consider using fiddler.

    You could turn on "CONNECTS" in Fiddler, you can see the TLS/SSL version in Inspectors -> TextView

    About how to turn on the CONNECTS, you could refer to below image:

    More details, you could refer to below article.


    Best Regards,
