Plesk for Linux kb: how-to
- Plesk for Linux
Does Plesk support the TLS protocol of 1.3 version?
- The support of TLSv1.3 was implemented in Plesk Obsidian and can be enabled for websites that are running on Nginx.
- At the moment only RHEL 8, CentOS 8, Ubuntu 18.04 and Debian 9 have an OpenSSL of 1.1.1 version which is required for TLSv1.3 support by Apache. TLSv1.3 is enabled for these OSes by default.
- The support of TLSv1.3 for the Plesk web interface is not implemented. Vote for this implementing of this feature. Top-ranked suggestions are likely to be implemented in product future updates.
- Plesk Onyx does not support TLS version 1.3, and its support is not planned.
