I am facing issue while renew certificate

I had added the custom domain and generated ssl certificate and then removed domain and setup again the same domain but this time I can’t renew SSL certificate and getting error as:

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our [troubleshooting guide](https://docs.netlify.com/domains-https/troubleshooting-tips/#certificates-and-https) for more information on how to fix the problem, and then renew the certificate.

So please guide me to fix this and also want to know when I setup the all DNS name servers into GoDaddy nameservers, the website is redirecting to the netlify domain instead of custom domain. why?

Thanks in advance!

I’ve routed this request to our helpdesk, we’ll follow up via email.
