Internal network use only - Access Denied

Internal network use only - Access Denied

  
Hello,

I have succesfully installed 9 on MS Server 2012R2.
However, I cannot connect to the platformserver with servicestudio when I use the public-ip
when I connect on the server itself with the internal ip or 127.0.0.1 it works.
but when using the public ip i get the following error "Internal network use only - Access Denied"

I am not sure how to solve this..


well, the issue went magically away after some serious rebooting, changiung subnets etc. etc,
