Nginx – TLS v1 enabled in nginx config but not working and certificates not available

I have an Ubuntu 18.04.1 server running PHP 5.6 with Forge on Digital Ocean. I'm trying to to enable TLSv1 and TLSv1.1 for a site. So Ive edited my NGINX config to include them:

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

Restarted NGINX and done a check with:

openssl s_client -host mydomain.co.uk -port 443 -tls1

which returns:

no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 7 bytes and written 0 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
No ALPN negotiated
SSL-Session:
    Protocol  : TLSv1
    Cipher    : 0000
    Session-ID:
    Session-ID-ctx:
    Master-Key:
    Start Time: 1537432315
    Timeout   : 7200 (sec)
    Verify return code: 0 (ok)
---

So I've tried to create a new certificate with Let's Encrypt in Forge and activated it, restarted NGINX and checked again which returned the same response.

Any ideas, i'm not sure what i'm missing to get this working.

Edit: Full NGINX config:
