SAP Server IP Change

Dear experts,

I had to assign a new IP adress to the SAP Business One Server.
I changed the IP and restarted the Server/Services.

I couldn't access the Integration Framework, so I thought I try to re-install.
But I can't install it anymore...

When I start the setup.exe, I dont get past the SLD connection/login.
Because obviously my IP has changed..

Is there a way around? Or do I need to re-install the SAP Server?

Your help is much appreciated.

Kind regards,

Giano
