If I give them the https://www.my-very-long-host-url.tld/:2083, that's secure but they have a weird address with a name without means with me... and worst, because the SSL cert is self generated, they'll have an browser alert about that.
If I give them a secure link with another domain name or IP, they'll have always the browser alert even they trust that.
So I asked to my host to install my own SSL cert, but he says it's not possible to use another SSL cert because "everybody could use my SSL cert.".
How do you handle that with your customer ? I always get a non secure link with my previous shared plan and I think it's not very secure...
And is it possible with CPanel to have several SSL cert, one for each reseller for example... like you have your own nameservers !
