Confluence Server get crashed when accessed with ssl
Asked by krishna_v:

I have a plugin in Confluence. After activating the plugin and using it, I cannot access my Confluence server with https but can access it with http. Is it related to server.xml file of Confluence server? The following is the catalina logs.

body: Your SSL config is broken somewhere, but it's impossible to tell where. We don't know how you have set up SSL.

But, also, you say this is caused by adding an add-on? What happens if you remove it and try https? What is the add-on?
