Can TLS 1.3 be enabled in Plesk?

Applicable to:

Plesk for Linux

Question

Can TLS 1.3 be enabled in Plesk?

Answer

TLSv1.3 support was implemented in the Plesk Obsidian 18.0 version for customers’ websites that are served by nginx and accessed by HTTPS.
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.
At the moment, only Ubuntu 18.04, by default, has an OpenSSL version 1.1.1 which is required for TLSv1.3.
