Error during SSL Handshake with remote server

问题:

I have Apache2 (listening on 443) and a web app running on Tomcat7 (listening on 8443) on Ubuntu.

I set apache2 as reverse proxy so that I access the web app through port 443 instead of 8443. Besides, I need to have SSL communication not only between browser and apache2 but also between apache2 and tomcat7, thus I set SSL on both apache2 and tomcat7. If I try to access the web app by directly contacting tomcat7, everything is fine. The problem is that when I try to access the tomcat's web app through apache2 (reverse proxy), on the browser appears the error:

Proxy Error
The proxy server could not handle the request GET /web_app.
Reason: Error during SSL Handshake with remote server

The comment by MK pointed me in the right direction.

In the case of Apache 2.4 and up, there are different defaults and a new directive.

I am running Apache 2.4.6, and I had to add the following directives to get it working:

SSLProxyEngine on
SSLProxyVerify none 
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off

Faced the same problem as OP:

• Tomcat returned response when accessing directly via SOAP UI
• Didn't load html files
• When used Apache properties mentioned by the previous answer, web-page appeared but AngularJS couldn't get HTTP response

Tomcat SSL certificate was expired while a browser showed it as secure - Apache certificate was far from expiration. Updating Tomcat KeyStore file solved the problem.
