Router Error after Import from local xampp?

Hi, I want to import a running wp site from xampp to local.

Zipping the folder + SQL file exported from database via phpmyadmin.

In local “Import Site”. After Import, view site: I get browser message after about 1 min waiting time

Local Router Error

Our apologies for the inconvenience. The Local router is not able to connect to the site you requested.

We suggest you try the following:

    Restart Site - Go to the Local by Flywheel app and restart the site you are attempting to access.
    Contact us - If the issue persists please contact us.


Newly created sites with local work fine. How can I fix that?

Thank you!
