TLS Versions
You can configure TLS versions as required.
Background
TLS is a security protocol used to ensure security and data integrity for Internet communication. The most typical application is HTTPS. TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 are available. A later version is more secure, but is less compatible with browsers of earlier versions.

Constraints
- Before configuring the TLS versions, configure an international HTTPS certificate first. For details, see Configuring an HTTPS Certificate.
- If the domain name is bound to a certificate with Chinese cryptographic algorithm, TLS versions cannot be configured.
- If you change the certificate type from International to Chinese (SM2), TLS version settings will become invalid.
- If you configure two certificates for a domain name, TLS version settings take effect only for the international certificate.
- You can enable a single version or consecutive versions. For example, you cannot enable TLS 1.0 and TLS 1.2 but disable TLS 1.1.
- You need to enable at least one version.
- By default, TLS 1.1, TLS 1.2, and TLS 1.3 are enabled.
- TLS versions cannot be configured for domain names with special configurations.
