SSL Binding is set but stops working

I have a self signed cert which I use to set the HTTPS SSL Binding on a web site.  This is the only web site on this server.

The server is Windows 2008 R2, IIS7

I works for days, then without warning will stop working.  IIS is still running and the web site still works at browsing using http is working.

If i check the bindings the SSL binding is there an unchanged.  If i just look at the SSL binding, and re-save without changing a thing, it starts working again.

While HTTPS is not responding I cam able to get connection with Telnet on port 443, although it returns nothing, a connection is made.

This is not a firewall issue,  software firewalls are turned off,  this happens locally on the server itself or from another system.

This is happening on multiple servers within different domains and environments.

Any help is greatly appreciated.

Dear mcrman,

What you mean on "return nothing" ? What is browser output look like or said  when you are using
https ? Could you capture it to us  to  take a look at ?

While HTTPS is not responding I cam able to get connection with Telnet on port 443, although it returns nothing, a connection is made

Just that, telnet returns no text and just disconnects,  if i use telnet to port 80 as soon as I type something and press return, IIS returns

I tried the steps outlined in the articles.  All say i have a good cert.

The SSL Binding needs to be re-saved after a reboot.  Always.
