Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
When I am trying to generate the _acme key, for this domain, I am getting the below error message
As you mentioned in the earlier responses, we are using certifytheweb and also POSH ACME.
Below is the error in POSH-ACME
Submit-ChallengeValidation : Authorization invalid for tableau.healthdataroof.io: No TXT record found at
At C:\Program Files\WindowsPowerShell\Modules\Posh-ACME\4.20.0\Public\New-PACertificate.ps1:253 char:9
The main this with DNS validation is to ensure the TXT record is being created (in your public DNS) and allow enough time for TXT records to copy to all of your nameservers, usually 30-60 seconds for Cloudflare, before proceeding with validation. Certify The Web will default to at least 60 seconds for Cloudflare DNS, I'm not sure about Posh-ACME.
