How to make sure open source server is running correctly

piSignage server is built upon MEAN stack.

Make sure 

• mongod is running without errors and listening at port 27017
• node is running  and message on console should mention  "listening at port 3000"
• Watch for any errors in the node.js command console
• Make sure the port 3000 is open for external access in your server 
• load the url http:// {{your server address}}:3000 in Chrome Browser and the server UI should be loaded

If pi is not reported at server 

• Check whether the pi player is able to ping server address 
• make sure port 3000 is added in the server field at the pi player
• Try using http:// {{your server address}}:3000 instead of just {{your server address}}:3000
• if you have edited package.json file make sure there are no syntax errors
• There is no firewall blocking port 3000
• Check the player log "tail -200 /home/pi/forever_log"
