Connection time out when trying to call the application for the first time

[cknebel]

I have installed everything on OpenShift like described in your manual (as a newbie to OpenShift I can say, that it really is easy to use and to understand). But when trying to start my application for the first time the request needs many seconds and then an error "[Warning] mysqli::mysqli(): (HY000/2002): Connection timed out" occures. I have already tried to set the database name manually, and "rhc env list -a cycleddorf" returns the right CYCLE_DB_NAME for my case.
What is strange that no other "rhc env" variables are present - no, db login, no password etc. Is this the problem?

Additional note: When enabling phpmyadmin in OpenShift I am able to connect to MySQL and see the database I want my project to run on "cycleddorf". So I can eliminate the error at OpenShift server.
