Switching to HTTPS via Cloudflare

I did not have any problems changing nameservers for my domain to the cloudflare service in order to get a secure URL. My site appears promptly, green lock instead of a notice of not secure connection, all pages almost complete. Although my site elements promptly load, the load continues and then eventually times out, with the result that my PayPal buttons never appear. There is a TLS handshake hang and eventual time out with "preview-editor.homesteadcloud.com", see pic. Can you remedy this? Or tell me how to remedy this? Would really like to maintain the https and still use Homestead. Thanks!
