This is the infamous 'browser-popup' problem: the 'CA' that signed your 
servers' certificate (in your case most likely a self-signed certificate 
but that's the same problem) is not recognized by your clients.

As in: the client receives the server certificate, tries to verify it 
against its repository of 'trusted CAs' and sees it can't do that.  And 
then generates the warning.

There are two ways to get rid of the message:
-get a server-certificate from a CA that is trusted by the clients; if you 
only care about the encryption and just want to get rid of the popup get 
a server-cert at http://www.freessl.com/, it will be ~40 euros.
-install the CA certificate that issued your server-cert (or your 
server-cert itself) in all connecting clients

In your situation the first option might be cheapest.
