VRay DR: could not connect to host 'XYZ'. An attempt was made to access a socket.....

[guenther Malek]

This question has been asked years ago already without any helpful reply:

 

VRay DR message:

"... could not connect to host 'XYZ'. An attempt was made to access a socket in a way forbidden by its access permissions..."

 

I already ran a Backburner Job, (which is, supposedly, neccessary)

I opened Firewall for Port 20204 und 30304

 

Still get that message.

Do need fixed IP addresses or does VRay DR also work with DHCP?

 

Does anyone know what it means, and what i can do about it?
