SSL Certificates over Wordpress Multisite with Cloudflare

I get intermittent 523 error on some of my websites which are on Jelastic Server. I checked with the server provider and they couldn’t find anything wrong.

Other websites which are not on cloudflare but on the multisite they work just fine without problem

Examples are: sponsorman.com, ticinoweb.net, zweitech.ch (cloudflare)

523 means that Cloudflare is not able to connect to the remote host.
I am not able to connect to sponsorman.com at all, ticinoweb.net gives me a 523 and zweitch.ch gives me an error because the certificate does not have the correct name on it.
