I have just purchased Wowza Streaming Engine. I had a demo 4.1.0 version working until now but has expired. I have applied my new license keys but I get a message saying that they are not valid. I have proceeded to upgrade to version 4.2 as suggested by our partner. Now, I get the ‘Wowza Streaming Engine could not connect to the Internet to validate your license key’ error. I see that there’s an article about this: [https://www.wowza.com/docs/troubleshoot-wowza-streaming-engine-licensing-errors-at-startup](https://www.wowza.com/docs/troubleshoot-wowza-streaming-engine-licensing-errors-at-startup) However, all of the proposed solutions suppose that the internet connection exists. In my case, company policy prevents our servers to connect to the internet, as a security measure. How do I license my WSE without internet connectivity? ---

Hello there. I have seen this request in the forums before. I think if you email support@wowza.com they will be able to answer this question for you or direct you to the correct department that can. Best, Salvadore ---

Hi, Are you able to connect to the internet using a web proxy server? In this case you can [configure your Wowza Streaming Engine to use proxy server to communicate with the license server](https://www.wowza.com/docs/how-to-configure-wowza-media-server-to-use-proxy-server-to-communicate-with-license-server).

How do I get IP’s if DNS is not working for my agency. ```auto *[license-server-ip]* wowzalicense1.wowzamedia.com *[license-server-ip]* wowzalicense2.wowzamedia.com *[license-server-ip]* wowzalicense3.wowzamedia.com *[license-server-ip]* wowzalicense4.wowzamedia.com ``` ---

Run this command in a terminal and you will retrieve all ip addresses you are actively using at the time. I would suggest you consider running the command at maintenance windows and updates to capture any changes. ```auto dig wowzalicense-all.wowzamedia.com ``` ---

Be difficult otherwise without a DNS working. Could try a proxy if the terminal command doesn’t work for some reason.
