Update:

i found out that the nginx file for the other site routes was not set up properly. to fix, i vagrant ssh into the box

cd /etc/nginx/sites-available 

LS to see all the files. In my case i only saw homestead.app.

create a nginx file with your correct configurations.

sudo vi /etc/nginx/sites-enabled/{app name.app}

here are the nginx configurations changed to reflect my app route. im not sure if my ssl changes are correct:

server {
       listen 80;
       server_name {myapp}.app;
       root "/home/vagrant/Code/{myapp}/public";

       index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/{myapp}.app-error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

    location ~ /\.ht {
        deny all;
    }
}

server {
    listen 443;
    server_name {myapp}.app;
    root "/home/vagrant/Code/{myapp}/public";

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/{myapp}.app-ssl-error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

    location ~ /\.ht {
        deny all;
    }

    ssl on;
    ssl_certificate     /etc/nginx/ssl/{myapp}.app.crt;
    ssl_certificate_key /etc/nginx/ssl/{myapp}.app.key;
}

save the file and run

sudo service nginx reload

and your sites should now be available given all other configurations(etc/hosts and homestead.yaml) are done and pointing to the right places.
