About this tag
The acme challenge tag covers discussions about DNS challenges used in the ACME (Automatic Certificate Management Environment) protocol for certificate validation. A common issue involves Active Directory DNS servers failing to resolve TXT records created by ACME clients in external DNS zones like Cloudflare, preventing certificate validation.

This tag is relevant for IT professionals managing hybrid DNS environments with on-premises AD and cloud-based DNS services.
