CNAME setup issue: 'https://frontend.theomer.co.uk’s server IP address could not be found.'

[TheoMer]

Hi,

So I've established a cname (alias) for my domain theomer.co.uk as follows:

name: frontend

which I attempt to access as follows:

https://frontend.theomer.co.uk

but results in the above mentioned error. What's the issue here?

Hi @TheoMer. Thanks for being part of GoDaddy Community! It looks like you have your CNAME pointed toward a Heroku site. Since the error mentions an IP address, my guess would be that there is an issue with the way the URL you're specifying in the CNAME resolves. I'm not seeing that error currently, though I am seeing an SSL error when visiting HTTPS://frontend.theomer.co.uk. That would probably be due to no SSL certificate being installed for your URL on the destination server. I'd review both situations with Heroku to see how you can resolve them.
