for those not using a Staticfile might wanna try this.
I had the same problem with nginx serving angular.
The following is the default config file, probably found somewhere in /etc/nginx/sites-available/yoursite
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
but what we acctually want is…
location / {
# First attempt to serve request as file, then
# as directory, then redirect to index(angular) if no file found.
try_files $uri $uri/ /index.html;
}
