OpenVPN Support Forum

We purchased 10 licenses for openvpn but when we tried to install them we received this message:

> LicenseActivate: <Fault 9000: "twisted.internet.error.DNSLookupError: DNS
> lookup failed: address 'licensing.openvpn.net' not found: [Errno -3]
> Temporary failure in name resolution.">

The ping responded though

after talking with support we discovered that, as can be seen above, licensing.openvpn.net is an alias in DNS servers
for licserv.openvpn.net which is the real URL. The licensing program was not finding an IP address for
licensing.openvpn.net

As a workaround you can, at least in linux versions which use /etc/hosts, and an entry to /etc/hosts

208.43.135.44 licensing.openvpn.net

I am sure there is a similar Windows file, but I am not too familar with windows.

But if you have that problem above, try this workaround.

In windows same file is located in %systemroot%\system32\drivers\etc\hosts
