I'm trying to connect from my Heroku app to a mysql db (Xeround) in an object-oriented way:
$this->db = new mysqli(
Credentials::databaseHost(),
Credentials::databaseUsername(),
Credentials::databasePassword(),
Credentials::databaseName());
(for clarity--> this line is located within the constrcutor of a central dispatcher I use. The sql connection is injected by this dispatcher if needed)
In my locally running production environment everything is working fine, however once I test it on Heroku the app hangs at the above point. No error msgs.
Any suggestions?
