Certificate errors - Too many failed and Certificate does not match name

It says that the certificate for my site: [www.matai.org/) is no longer valid.
When I try to renew the certificate on Netlify it says: “We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved”

with the full error message being:
Acme::Client::Error::RateLimited: Error creating new order :: too many failed authorizations recently: see Failed Validation Limit - Let's Encrypt

This followed a previous message of:

Certificate does not match name www.matai.org

SniCertificate::CertificateNonvalidError: Unable to verify challenge for matai.org: 2620:1ec:46::71: Invalid response from MATAI 400

I’m not quite sure why the certificate is no longer valid and I am unable to renew the certificate.

Any help with this is greatly appreciated.

Hey @chrisgits,

This appears to be resolved.
