nginx: [emerg] “server” directive is not allowed here in /etc/nginx/nginx

Attempting to use this

The example as linked above is valid (the server directive is in the http context, see nginx documentation). If you modified the config and it’s not valid anymore then you need to share your modified version of the config, otherwise we can’t help.

nginx: [warn] invalid value “TLSv1.3” in /etc/nginx/nginx.conf:94

From this config

Had to switch

    ssl_protocols TLSv1.2 TLSv1.3;

to

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

to get to a certificate error. maybe its working now.

6

Error, has me stumped,

SSL_CTX_use_PrivateKey_file("/path/to/private_key.key")

How do i generate this if certbot fails to load

You could probably get by with a much simpler setup. Diaspora* nginx reverse proxy config · GitHub is what I used today with a docker-compose deployment.
