Nginx configuration failed

I already have an Nginx server running as a proxy pass for various other web services, so my nginx config is already perfectly valid.

I run the sudo ee site create example.com --wp command to start a new wordpress site but it just immediately gives me an NGINX configuration failed error.

After this it creates a new file called 22222 in my sites-available directory. doing a test with nginx -t gives me: nginx: [emerg] "tcp_nopush" directive is duplicate in /etc/nginx/conf.d/ee-plus.conf:6
nginx: configuration file /etc/nginx/nginx.conf test failed. If I delete this file then nginx works fine as usual again, so ee is creating an invalid configuration somehow.
