After manually creating my sub-domain multi site I am unable to access site

I created a new site for the first time in my new multi site network and it seemed to create the sub-domain just fine. But when I went to access the sit URL and/or the WP-Admin, my browser said that the site could not be found.

So I went a little further and tried updating the network to see if that would make the site appear and this message popped up.

Hope you guys can help me wit this :slight_frown:

Cheers :slight_frown:
