If you are experiencing this problem when using Docker be sure to map the correct port numbers. If you map port 81:80 when running docker (or through docker-compose.yml), your nginx must listen on port 80 not 81, because docker does the mapping already.

I spent quite some time on this issue myself, so hope it can be to some help for future googlers.

You have to go to the  etc nginx sites-enabled  and if this is the default configuration  then there should be a file by name  default   Edit that file by defining your desired port  in the snippet below  we are serving the Nginx instance on port 81   server       listen 81      To start the server  run the command line below   sudo service nginx start   You may now access your application on port 81  for localhost  http   localhost 81

You will need to change the configure port of either Apache or Nginx  After you do this you will need to restart the reconfigured servers  using the  service  command you used     Apache  Edit  sudo subl  etc apache2 ports conf    and change the 80 on the following line to something different    Listen 80   If you just change the port or add more ports here  you will likely also have to change the VirtualHost statement in  sudo subl  etc apache2 sites-enabled 000-default conf   and change the 80 on the following line to something different     lt VirtualHost   80 gt    then restart by    sudo service apache2 restart     Nginx  Edit    etc nginx sites-enabled default   and change the 80 on the following line    listen 80    then restart by    sudo service nginx restart
