Windows 8.1 only using TLS1.0 for SSL protocols
Accessing an https site using win8.1 and ie11 only uses TLS1.0 whatever combination of SSL3.0/TLS1.0/TLS1.1/TLS1.2 are enabled in IE11 tools/internet options/advanced. I investigated and found that I had this problem with a site (community.serif.com) that is only enabled for TLS1.1 and TLS1.2.  Automatic update is on so I have the latest versions.  I verified that only TLS1.0 is offered in the 'client hello' TCP using wireshark.

Hi,

After reading your question, I guess you mean the website you mentioned is designed for TLS1.1 and TLS1.2, but you only find TLS1.0 in the package which you captured by using wireshark.

I would like to know whether the issue occurred in only one website. I suggest you can try to disable TLS1.0 in Internet Options and then capture the package again.

In addition to that, you would better to ask the website administrator to know more information about the website due to the website doesnt managed by Microsoft and we are not certain which security protocols the website really use.

      

Best Regards

Thank you for your reply.Most web sites seem to be able to support TLS1.0.  Problem only came to light when I tried community.serif.com which as you say only supports TLS1.1/1.2. Investigating other browsers and web sites on my Win8.1 with wireshark I could only get TLS1.0 in the package.  By elimination my Win8.1 seems to only support TLS1.0 based protocol.  I cannot find any means to enable TLS1.1/1.2 in Win8.1.  It is supposed to support them.  I think if any TLS (or SSL3) is enabled in IE, my Win8.1 defaults to TLS1.0 and works with any site that includes support for TLS1.0.

I have emailed site administrator but they replied they used TLS1.2.

I have tested their site with https:// globalsign ssllabs com/analyse html?d=community serif com and sure enough they only support TLS1.1/1.2. (replace spaces with stops in URL except first one)

This does appear to be a problem with my Win8.1.
