Hi Manuel,

At the moment this not possible, unfortunately.
However, this is only during the version checking step of launching Cube. If you have an existing Cube open (for example by connecting to another DMA or cluster), you can logout there, then on the login screen press CTRL-ALT-SHIFT to change the hostname into an editable textbox. Then enter the hostname there. This should allow you to access the DataMiner system until a proper certificate can be configured.
