Err_cert_common_name_invalid

Hi @Vitaleak,

Thanks for reaching out and welcome to Netlify’s Support Forums!

I’m sorry to hear about the issue with the error. Reviewing the DNS for www.vitaleak.com, I do see that the CNAME Record is correctly pointing to vitaleak.netlify.app.

host www.vitaleak.com
www.vitaleak.com is an alias for vitaleak.netlify.app.
vitaleak.netlify.app has address 35.169.59.174
vitaleak.netlify.app has address 18.213.222.111
vitaleak.netlify.app has IPv6 address 2600:1f18:16e:df00::64
vitaleak.netlify.app has IPv6 address 2600:1f18:16e:df01::64

However, the A Record for vitaleak.com is not pointed to Netlify’s Load Balancer IP 75.2.60.5:

host vitaleak.com
vitaleak.com has address 198.49.23.145
vitaleak.com has address 198.185.159.144
vitaleak.com has address 198.185.159.145
vitaleak.com has address 198.49.23.144
vitaleak.com mail is handled by 10 mxa.mailgun.org.
vitaleak.com mail is handled by 10 mxb.mailgun.org.

You’ll want to update the A Record so that it’s pointing to 75.2.60.5. We have a Support Guide here that can help:
