Ngix configuration for two odoo instances

I want to run multiple subdomains on same server each connected to a different odoo instance and all instances are running on different ports. However, I can't get one of the subdomains working, here are my configuration files, I know only one of them is the subdomain and other one is proper domain, but the you can get the idea:

example1.com.conf

# Odoo servers
upstream odoo {
 server 127.0.0.1:8030;
}

upstream odoochat {
 server 127.0.0.1:8072;
}

# HTTP -> HTTPS
server {
    listen 80;
    server_name www.example1.com example1.com;

    include snippets/letsencrypt.conf;
    return 301 https://example1.com$request_uri;
}

# WWW -> NON WWW
server {
    listen 443 ssl http2;
    server_name www.example1.com;

    ssl_certificate /etc/letsencrypt/live/example1.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example1.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/example1.com/chain.pem;
    include snippets/ssl.conf;
    include snippets/letsencrypt.conf;

    return 301 https://example1.com$request_uri;
}

        proxy_pass http://odoo;
    }

example2.mydomain.com

}

example1.com is working just fine, however, whenever I click on anything on example2.mydomain.com it will redirect me to the name to upstream so for example:

• There is a button that will take me to example2.mydomain.com/web
• Upon clicking it will take me to example2/web instead
• If I manually input example2.mydomain.com/web in URL it will work just fine

I have gone through documentations, articles etc but can't figure out what I am missing in the configuration? Id it odoo thing because default odoo & odoochat upstreams are working but not the custom one that I have defined.
