Import a migrated database

I used trudesk on a Windows machine and am moving it to an Ubuntu one. I want to keep my database. I was able to import my database using mongodump and mongorestore, and then connect to it with trudesk installation, but now I can’t get past “service unavailable” when I go to Localhost:8118.

What am I doing wrong?

Look at updating the config.json file to connect to the new database.
Beyond see the log files it may be difficult for me to troubleshoot.
