I think you should change


server {
listen 80;
server_name ~^(.+)\.mydomain\.com$;
location / {
root /home/$1/public_html;
index index.html index.htm;
}
}

to


server {
listen 80;
server_name ~^(.+)\.mydomain\.com$;
set $name $1;
location / {
root /home/$name/public_html;
index index.html index.htm;
}
}
