V-Ray error: Could not obtain a license (-7)

Error: V-Ray error: Could not obtain a license (-7): The ChaosGroup License Server is denying access. Update the license server and check access filter (if any).
at Deadline.Plugins.PluginWrapper.RenderTasks(String taskId, Int32 startFrame, Int32 endFrame, String& outMessage, AbortLevel& abortLevel)

This started last week with Vray not wanting to render in both Maya 2019 IPR and Deadline Monitor 10. This was the error code that we are receiving when trying to render through Deadline. When using IPR Maya 2019 it just crashes the scene and sometimes freezes the whole computer. I have tried to delete the preferences and folders. I also tried uninstalling and reinstalling Vray. I also tried to update to Maya 2020 and update Vray to the latest expect for 5, and it still won't render in Maya 2020 IPR. Lastly I tried to go into the license settings and make sure the default TCP port was at 30304 and making sure the IP address was correct for the computer I use.

Is there something else that I can do to start using Vray again?

Any help would be great.

Thank you.

Hello, in such cases it's always better to submit a ticket (details as your email associated with the licenses are not recommended to be shared on forums and we need that info) and provide information regarding the currently installed versions of V-Ray. Also screenshot from the http://localhost:30304 page is also very useful:
