DR : could not obtain a license vray 3.504

Hello I just installed the last public build, but none of the slave works.
I got “could not obtain a license”.

Thanks

reinstall license server?

You need to verify the license server is running and you can see your licenses listed when you navigate to http://localhost:30304 on the license server machine. If there’s a problem - try reinstalling the license server - https://download.chaosgroup.com/downloads/2127/licenseserver-standalone-431-adv

Also - make sure the license settings are correctly configured on the nodes - Chaos Docs

Thanks,
problem solve by deleting the ENU file.
