Question

Can TLS 1.3 be enabled in Plesk?

Answer

TLSv1.3 support was implemented in Plesk Obsidian 18.0 version for customers’ websites. TLSv1.3 support can be enabled for websites that are served by nginx only and accessed by HTTPS.
At the moment, only Ubuntu 18.04 and Debian 9 has an OpenSSL version 1.1.1 which is required for TLSv1.3 for Apache. TLSv1.3 is enabled for these OSes by default.
TLS v1.3 is not supported yet by Plesk Obsidian interface web server(sw-cp-server).
Plesk Onyx does not support TLS version 1.3, and its support is not planned.
