Error: Could not obtain an interface license (-200): The ChaosGroup License Server could not be reached.

how do i fix this ?

Make sure V-Ray Licence Server is up and running, error -200 means V-Ray cannot reach it.

Please mind that V-Ray 3 trials use online licensing:

1. Make sure when installing V-Ray 3 to install also the Online license server. It can be downloaded from https://download.chaosgroup.com/down...dalone-451-adv

2. Navigate in your browser to http://localhost:30304

3. Log in with your username - https://docs.chaosgroup.com/display/...lineActivation

4. Restart Maya and try to render

I am also experiencing this same error message ( // Error: Could not obtain an interface license (-200)! //) and have gone through the checklist provided:

- i am still using a dongle but I have the online license server installed
- i am able to see the status of my licenses - it says i have 2 V-RAY FOR MAYA 3.0 interface license available
- i am logged in successfully and can see my user name and machine in the online license server
- i have restarted maya and rebooted machine

additional information:
- dongle is in a USB 2.0 slot, on the same machine I am using Maya
- Maya 2015 -x64
- Vray for Maya 3.10.01
- running on CentOS 7.4.1708
- WIBU Key drivers are installed for the dongle

I'm not sure what next steps I can take for troubleshooting - any suggestions anyone?

many thanks!

You can check if the license settings are correct. In Unix - based OS they are set usually per user (unless a variable is set to point to a centralized location of the file, containing the license info). You can use the localhost IP address if the dongle is plugged in the same machine, for example:
$ sudo /usr/autodesk/maya2015/vray/bin/setvrlservice -server=127.0.0.1 -port=30304

Thanks a lot Ivan, you were correct about the setvrlservice not having the correct information, thanks for steering me in this direction.

One note for anyone else troubleshooting this is to make sure you are truly modifying the file. When I ran the above command with the correct ip addresses etc it would confirm 'Settings updated' - when in actuality it hadn't. By running the command with the -dump flag I could see that nothing had changed. On my system everything in the /usr/autodesk/maya2015/vray/bin folder is owned by root so by logging in as su I was able to successfully update the file and now everything works : )
