Question

Hi, I'm having issues setting up ssl certificate on digital ocean.

I followed this tutorial https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04

and when I write this command sudo certbot --nginx -d example.com -d www.example.com with my own domain, I get this error

Challenge failed for domain goldenpay.click Challenge failed for domain www.goldenpay.click http-01 challenge for goldenpay.click http-01 challenge for www.goldenpay.click Cleaning up challenges Some challenges have failed.

IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: goldenpay.click Type: dns Detail: DNS problem: SERVFAIL looking up A for goldenpay.click - the domain’s nameservers may be malfunctioning; DNS problem: SERVFAIL looking up AAAA for goldenpay.click - the domain’s nameservers may be malfunctioning

Hi there,

Indeed, in order for Let’s Encrypt to be able to validate your domain name, you need to first change your A record to point to the server’s IP address.

You can follow the steps on how to do that here:
