No longer able to login to the web GUI using a browser other than IE or Firefox

Hello! It seems opscenter is not configured correctly or the HTTPS settings are not secure enough. Here is the message I get when I try to login with Opera:

Server has a weak ephemeral Diffie-Hellman public key

This error can occur when connecting to a secure (HTTPS) server. It means that the server is trying to set up a secure connection but, due to a disastrous misconfiguration, the connection wouldn't be secure at all! 

In this case the server needs to be fixed. Opera won't use insecure connections in order to protect your privacy.
 

A quick search on the web points me to a weak key (smaller than 1024bit) being used for the https connections. Where/how can I fix this? The other browsers allow me to connect but I would prefer not using IE or Firefox...
