nginx domain resolves to incorrect site

I’m trying to host two domains on a single droplet. domainA.com and domainB.com

domainA.com correctly shows content from /home/public/domainA/index.php correctly. domainB.com just shows domainA.com, whereas it should be showing the content of /home/public/domainB/index.php.

Both domains are using digitaloceans nameservers, have an entry in sites-available and sites-enabled.

domainA nginx config:

server { listen 80;

    root /home/public/domainA/;
    index index.php index.html index.htm;

    server_name domainA.com www.domainA.com;

…

domainB nginx config:

server { listen 80

    root /home/public/domainB/;
    index index.php index.html index.htm;

    server_name domainB.com www.domainB.com;

…

Any help resolving this matter would be much appreciated!

Thanks
