Question

How do I enable TLS 1.3

Apache 2.4.46; Ubuntu 16.04

I have set

SSLProtocol -all +TLSv1.2 +TLSv1.3

In

/etc/apache2/mods-enabled/ssl.conf

And restarted, but it doesn’t seem to have enabled TLS 1.3

Hi @MPA,

Make sure you’ve added it inside the module mod_ssl.c

<IfModule mod_ssl.c>
---Code goes here
</IfModule>

Another thing, check if the ssl.conf file in mods-enabled has a symlink to mods-available

ssl.conf -> ../mods-available/ssl.conf

If it doesn’t you’ll need to either make the symlink or manually update the mods-available/ssl.conf as well.
