Automatic repeated logon to web app

I have a multi tenant mvc web app hosted on a shared server. Users log on with login credentials (username and password). The app stores data in an sql server database.
When no user has been logged on for a while, the start-up time for the first user to log on is quite long.

Can I use Hangfire to set up a background job that starts the app in repeated (for example every hour) intervals?
