Vray/Blender can't add port 5555 to firewall

[I14R10]

I started using Ubuntu instead of windows, and I have a problem with Blender with Vray. During the install I get an error saying something like : "Firewall error: can't add port 5555" and "Firewall error: can't add application to exceptions". Blender works fine, but I can't get Vray to function. From the Blender console I get "Could not obtain a license (-98 ): There are no available licenses of this type on the ChaosGroup License Server.". But the license server works fine. I can open it from the browser and I can see my license there.
I tried disabling ufw firewall but it doesn't do anything. I tried to allow port 5555, but it also doesn't do anything. So, I could use some help here.

This is copy paste from installation log

Encountered errors during installation:
Firewall: FAILED to add port 5555
Firewall: FAILED to add exception for application: /usr/ChaosGroup/V-Ray/VRayZmqServer/VRayZmqServer
Error during: Updating Firewall

EDIT
And if I borrow a license for offline use I get this error "Could not obtain a license (-6): The ChaosGroup License Server is taking too long to respond."

Sorry to bother you, everything is fine. I've been trying to install Vray Next instead of Vray ADV and didn't even notice it. Works fine now.
