Failed to renew TLS certificate for my custom domain

Please help me re-provision a standard non-wildcard certificate for andreihagiu.com and [www.andreihagiu.com](https://www.andreihagiu.com)

My Netlify subdomain is peaceful-heliotrope-7bf93d.netlify.app

The error message I keep receiving is as follows:

SniCertificate::CertificateValidationError: Unable to verify challenge for *.andreihagiu.com: No TXT record found at _acme-challenge.andreihagiu.com

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our troubleshooting guide for more information on how to fix the problem, and then renew the certificate.

The certificate expired on July 28, and visitors now receive NET::ERR_CERT_COMMON_NAME_INVALID. My DNS is externally managed, and I do not need a wildcard certificate. Please remove/reset the existing certificate for *.andreihagiu.com and re-provision a standard non-wildcard Let’s Encrypt certificate for andreihagiu.com and www.andreihagiu.com. The site is peaceful-heliotrope-7bf93d.netlify.app.

I would really appreciate an answer as soon as possible. It’s been more than a week and my website cannot be accessed. Thank you in advance.
