title: IE TLS block how to move from TLS 1.0 to TLS 1.2 in tomcat 6 and java 6
body: <p>I am having a problem where explorer does not display a web site: "This page can't be displayed. Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings".</p>
  
  <p>I debugged the certificate in chrome and says "the connection is encrypted using aes_128_cbc" which I think is the problem and should be aes_256_cbnc</p>
  
  <p>I am comparing with other server that is working and that uses aes_256_cbc which IE supports. However don't know how to force the communication to use TLS 1.2 instead of TLS 1.0 (as with the connection against the server that works in IE).</p>
  
  <p>Both servers have the same version of java. It may be something setup in the load balancer but is something i cannot look at.</p>
  
  <p>What would be the best and/or quickest ways to change the tomcat connection to use TLS 1.2 instead of TLS 1.0 ?</p>
  
  <p>IE settings seem fine , simply won't accept https connections using aes_128_cbc. Tried to regenerate the certificate (using keytool) to use a key size of 2048 but had no effect.</p>
