SSL Connections Dropping

I recently enabled SSL with Cloudflare, but now users seem to get logged off a lot sooner than before. It seems like the connections are timing out sooner. Keep me Logged In doesn't appear to be working. Has anyone experienced this and how do I correct it?
I think I resolved this. I am running VaultWiki, and needed to select the option to force HTTPS. I had it in a flexible configuration before, which does not work because it will end the SSL session when it swaps back and forth.
