I have a Netlify site set up at https://escapingdystopia.netlify.app
I have a custom domain through NameCheap at escapingdystopia.co.uk
Yesterday, visiting https://www.escapingdystopia.co.uk successfully loaded the Netlify site (DNS connection is working fine). I pushed a new deployment today, and while https://escapingdystopia.netlify.app loads fine my custom domain returns " www.escapingdystopia.co.uk ’s server IP address could not be found."
I have tried cURLing it but the cURL returns “curl: (6) Could not resolve host: www.escapingdystopia.co.uk”
What are my next steps?
Changing the primary address to https://escapingdystopia.co.uk allows me to visit this site, however now going to https://www.escapingdystopia.co.uk (which should redirect me) doesn’t work at all. I’d ideally like the www. site to be my primary but it isn’t behaving with that as my primary. I’m new to all of this so don’t know where to go from here.
@james-work-account How long has your site been up? As you note, your apex domain loads but your www subdomain redirects to your apex domain, so I’m not seeing an error there. Your DNS settings appear on the surface to be OK, FWIW.
@gregraven I’d posted this after about an hour of trying to figure out what had gone wrong with my deployment to break the connection to my domain. I guess I just needed to wait a little longer 
the subdomain must’ve fixed itself some time in the last half an hour as it wasn’t working when I went for lunch. Serves me right for being impatient…
@james-work-account I know what you mean. I do the same thing all the time. Then, when I force myself to be patient and wait things out, it turns out that there is a problem somewhere that needs to be fixed, so I just wasted a bunch of time when it could have been fixed almost immediately. Still learning how to take my time in a hurry.
