Hi @MPA,

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

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

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.
