nginx: [warn] duplicate value when editing file in nginx/sites-available

I’ve just migrated my Wordpress / Woocommerce site to a new Ubuntu 20.04 droplet. (www.themusicvault.co.uk)

I’m trying to edit my nginx/sites-available config file to strengthen my SSL following this tutorial.

https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html#HTTP_Public_Key_Pinning_Extension

However im getting the following error when trying to add anything to my config file in sites-available.

nginx: [warn] duplicate value “TLSv1.2” in /etc/nginx/sites-enabled/themusicvault.co.uk:37

Any ideas what might be causing the issue?

Hi there @jak3tayl0r,

What I could suggest here is using the grep command to look for any other references of TLSv1.2 in your Nginx directory.

To do that, you can run the following command:

  1. sudo grep -ri 'TLSv1.2' /etc/nginx/

Also if you wish you could share the contents of your /etc/nginx/sites-enabled/themusicvault.co.uk file so that I could try to advise you further.
