new certificate with RSA4096/SHA256

Hi,

I've got a new certificate from our CA with key size 4096 bits (RSA) and SHA256 hash algorithm. (The old one has been 2048/SHA1). While opening the webinterface on this Connection Server Firefox tells me "ssl_error_no_cypher_overlap".

As I understand it, the available cipher suites aren't matching with the certificate. So i tried to create the locked.properties in <programdir>/Server/sslgateway/conf with "enabledCipherSuite...."

Now I see "Cannot support <cipher suite> with currently installed providers."

It's a Windows Server 2008 R2 with Horizon View 6.0.1.

Does anyone know what to do in this case?

thanks in advance!

best regards

Roland
