It seems Cisco is not keeping up with Microsoft IE updates. Hi Jitender, I think this is a different issue.

I have two customer with the same problem. I was able to check that this problem ocurred after some Windows updates. It's not affecting the CUCM Unfortunatelly, until now, we don't have a workaround for the Internet Explorer, but with Firefox is working with no issues. I have seen similar issue been reported, unfortunately i dont have exact BUG or explanation to the issue at this point but what i can tell you is it affects CUCM version 9.

X and below and IE 11 with different permutations combinations. What i can tell for sure is in our lab we tested with latest 9. I will keep testing and check if something changes after the next update.

If so, I will do another post. Microsoft released KB as an optional update in the June patch release. It is "June update rollup for Windows 7 SP1 and Windows Server R2". KB "Update to add new ciphers suites to IE and Edge in Windows" which is part of KB causes problems.

This patch stops IE accessing Cisco web pages using https, the error is "This page can't be displayed". Specifically it seems to change the minimum Diffie-Hellmen key length IE will accept from bits to bits and the Cisco Tomcat server can't offer KB talks about this and provides a registry entry which sets the minimum key length back to bits. It looks like Cisco Tomcat offers a bit key so you can set the registry entry to hex and not Had to create new key Diffie-Hellman but the rest worked like a charm.

Other alternative is to generate a CSR from cucn and give to CA to create SHA2 certificate for tomcat and upload the same. If you are using a proxy with IE make sure it is setup to bypass proxy server for local addresses. I just ran into this problem also. After uninstalling recent windows updates I was able to access the CUCM again. I don't know which of the multiple updates did this this just happened to me today but the next step is to re-install the updates one at a time and figure it out.
