Wordpress Multisite Subdomain Mapping Issue

I used the tutorials on this site to try and set up Wordpress Multisite with Subdomain Mapping on nginx. I have my main site working, but the mapping to subdomains isn’t happening.

I’m getting this:

The server at lifestylezero.webmissioncontrol.com can’t be found, because the DNS lookup failed. DNS is the network service that translates a website’s name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.

This is the tutorial I followed.

Any ideas why this would be happening?

Hey sorry for late reply.

Let us know if your issue is solved or not. Its seems like DNS is not propagate proplerly.

No problem - this issue was resolved. I changed so many variables I forget what it ultimately ended up being, but I think that I had errors in my nginx config file…
