API not able to connec to mongo

[skhani]

In running the docker image, i noticed, that localhost was not serving.
Sonar was running, mongo was running, jenkings was running.
logging into the Hygieia box, i did not see any logs and looks like the API was not running.
forcing to run the API i see errors which it is not able to connect to Mongo.
Any help here?
