Solved Another Lets Encrypt Certificate failed to renew

[THCO]

I received the following email and Im not sure what to do.

Lets Encrypt SSL certificate was failed to renew. Error: System.AggregateException: One or more errors occurred. ---> PostInstall.LetsEncrypt.LetsEncryptRegistrationException: Lets Encrypt authorization status 'invalid'. Authorization not completed. type : urn:acme:error:connection; detail : DNS problem: NXDOMAIN looking up TXT for _acme-challenge.xxxx.3cx.us; status : 400

How can I check to see if this renewed properly.

Thanks

Hello @THCO,

Please make sure that you can resolve www.letsencrypt.org correctly from the PBX machine and that nothing is blocking the communication between Let's Encrypt and the phone system.

This issue has been resolved, received another email the next night stating the cert renewed.
