Localhost: "This site can’t provide a secure connection"

Question

I have a server running on Tomcat on port 8080. When I go to localhost:8080 I see the proper Tomcat startup page. But, when I try to go to my desired app, which is running at localhost:8080/my-site I get a SSL-Error saying "This site can’t provide a secure connection". I cannot figure out what's wrong.

My logs in Tomcat refer to memcached, but I don't even think I'm running it. They read

2017-09-18 17:18:19.176 INFO net.spy.memcached.MemcachedConnection:  Connection state changed for sun.nio.ch.SelectionKeyImpl@44d6a8bb

I'm totally stuck here. Any and all help would be greatly appreciated. Thanks in advance.

Solution

Click 'Advanced' in the bottom left corner and then click something like 'proceed anyway. Your app is implementing HTTPS with a self signed certificate and you need to add it to your allowed CA list
