DNS configuration 2 domains

There is not a directive for wildcard subdomains, so you will be answer by first conf in line

server { server_name domain2.com www.domain2.com; … }

server { server_name domain1.ca www.domain1.ca; … }

it should be something around this lines:

server { server_name .domain2.com; … }

server { server_name .domain1.ca; … }

It worked, thank you!

If you want to support additional subdomains or have your site act as a catch-all for subdomains in that domain you would want to update your server_name parameter to look like this:

server {
server_name domain1.ca www.domain1.ca *.domain1.ca;
...
}

The addition of the *.domain1.ca tells nginx to serve requests for any name that ends with domain1.ca.
