Server has a weak ephemeral Diffie-Hellman public key

F-Secure PSB Server Security 11.00 build 236

 

When I try and connect to https://127.0.0.1:25023/ on a windows 2008 R2 server I'm receiving the following error message : - Server has a weak ephemeral Diffie-Hellman public key 

Does anyonw know why this is? Tried rebooting , turning off the firewall etc and also restarting the service but nothing seems to make a difference. Can anyone suggest any solution please?

Thank you.
