Cert

CADir

• Type: string
• Version：>= v2.0.0-beta.37

When applying for a Let's Encrypt certificate, we use the default CA address of Let's Encrypt. If you need to debug or obtain certificates from other providers, you can set CADir to their address.

TIP

Please note that the address provided by CADir needs to comply with the RFC 8555 standard.

RecursiveNameservers

• Version：>= v2.0.0-beta.37
• Type: []string
• Example: 8.8.8.8:53,1.1.1.1:53

This option is used to set the recursive nameservers used by Nginx UI in the DNS challenge step of applying for a certificate. If this option is not configured, Nginx UI will use the nameservers settings of the operating system.

CertRenewalInterval

• Version：>= v2.0.0-beta.37
• Type: int
• Default value: 7

This option is used to set the automatic renewal interval of the Let's Encrypt certificate. By default, Nginx UI will automatically renew the certificate every 7 days.

HTTPChallengePort

• Version：>= v2.0.0-beta.37
• Type: int
• Default: 9180

This option is used to set the port for backend listening in the HTTP01 challenge mode when obtaining Let's Encrypt certificates. The HTTP01 challenge is a domain validation method used by Let's Encrypt to verify that you control the domain for which you're requesting a certificate.
