How can I change the [fully qualified hostname] selected in the installation?

Good morning,
by mistake I selected the wrong fully qualified hostname during the installation.
Now, none of the links are working and I have to change it manually everytime I opne a window.
More info:
For the Jazz Team Server:Point your web browser to https://[fully qualified hostname]:9443/jts/admin
I wave read, that I need a file from IBM to change it.
Could you please send it to me or get me in contact with the right support tem?
Thank you and kind regards,
Javier Hernández
