mongodb not working after Lightsail MEAN instance upgrade

Question

Create a new Lightsail MEAN instance(2GB ram) using  snapshot from another Lightsail MEAN instance (512mb ram). Both instances are in same region. 
Everything working as except mongo db.

I am getting this error when trying to connect to MongoServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017

I tried to start mongo -  `sudo service mongodb start` and getting below message
`Failed to start mongodb.service: Unit mongodb.service not found.`

mongo was working in the previous instance. Should we do anything else after creating an instance from snapshot?

Any help is truly appreciated.

Answer

Not sure about what caused this. I created another instance from a previous snapshot and it worked magically. Strange though.
