Some HTTPS websites do not load in Microsoft Internet Explorer when running Windows 7.
Internet Explorer is trying to use TLS 1.2 to connect to secure websites.
TLS 1.2 is not supported in SGOS 6.4.x or earlier. TLS 1.2 support for this feature is included in SGOS 6.5.x.
Note: This issue does not occur in Google Chrome and Mozilla Firefox because they re-negotiate the connection and try to use a different protocol (TLS 1.0 or 1.1, SSLv2 or v3).
First, determine if the browser is trying to use TLS 1.2.
If you have verified that TLS 1.2 is being used, disable TLS 1.2 in Internet Explorer.
HTTPS websites should load correctly after TLS 1.2 is disabled in Internet Explorer. You can run another PCAP to verify that TLS 1.2 is no longer being used.
