You've already been told to only specify listen options once.  
That is, you should write

    server {
        listen [::]:80 ipv6only=on;
        ...
    }

    server {
        listen [::]:80;
        ...
    }

instead of 

    server {
        listen [::]:80 ipv6only=on;
        ...
    }

    server {
        listen [::]:80 ipv6only=on;
        ...
    }

in your config.
