Authentication failed when using invitation code

I installed Docker for Windows and when I submit the invitation code I get the below error. I am using Windows 10 laptop behind company proxy. Any suggestions?

Your laptop can’t reached Since you are behind the company proxy, you will need to check with your Network Admin to make sure the DNS is working correctly.

As an alternative to @fauzanariffin’s suggestion, if you’re on a laptop, you may also try to activate Docker from a freer network.

Thank you. I will try registering from home network since no change can be performed in my company DNS.
