Windows 10 KB3163018 Breaks CCM 9.0.1 SSL

After installing the Windows 10 KB3163018 update, you are no longer able to load Call Manager 9.0.1 web interfaces that use a self signed certificate.

There’s a bit of talk on the KB here:

And similar issues here for Viewmail on 11.5 –

I haven’t been able to check whether this is resolved with a properly signed certificate, or whether it’s a limitation in the tomcat library.

Interestingly it doesn’t impact 7.1.5 clusters. I will check against 11.0.1 shortly.

UPDATE: 11.0.1 works fine, just the usual self signed certificate warning.

  1. Appears to be TLS1.0 has been completely dropped. Test on enabling only TLS1.0 – works without the update, once installed you get “Page cannot be displayed”
