Cakephp3 phpmyadmin problem with de access



Hi people I have a problem developing in cloud9. I followed the steps to configure mysql and phpmyadmin. So when I run the app I do it with the following line: bin/cake server -H -p 8080. The apps run fine, but when a try to access phpmyadmin ( shows an error:Error: PhpmyadminController could not be found.
But when I run the app by running the index.php file (without bin/cake server -H -p 8080) works fine to access phpmyadmin.

So Basically this is my problem I want to run my application with the line bin / cake server -H -p 8080 and access phpmyadmin without any problem.
Thanks for the help.
