I found the issue. This issue caused due to sizing of my machine. It takes a lot of time ( more than 15 minutes) for my machine to go beyond “Snapshotting functions”. After showing patience from my side it worked.
P.S. This is my machine size

Thanks for the report @SameerPatil,

You may want to try disabling snapshotting in your manifest.yml to see if that improves your tunnelling experience.

    snapshots: false
