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

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.
