Redirects in laravel forge issue

Hi.

Im trying to redirect an old domain to the new domain through the nginx config, but it doesn't seem to work. I get ::

nginx: [warn] conflicting server name "my_domain.uk" on 0.0.0.0:443, ignored
nginx: [warn] conflicting server name "my_domain.uk" on [::]:443, ignored
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Here is the config::

server {
    listen 80;
    listen [::]:80;
    server_name .my_domain.ie;
    rewrite ^/(.*) https://www.my_domain.uk/ permanent;
}

Any ideas on how to resolve this? Both the sites are on the same server, so not sure if that's got anything to do with it or not!

Many thanks
