Hello @United_MFO
Check logs for errors with heroku logs --tail.
Verify database credentials in your .env file and Heroku config vars.
Run migrations and seeders manually: heroku run php artisan migrate --force and heroku run php artisan db:seed --force.
Clear caches with php artisan config:cache, php artisan route:cache, etc.
Check the Procfile to ensure proper web server setup.
Rebuild the app using heroku restart.
By following these steps, you should be able to identify where the issue is and proceed with completing the installation. Let me know how it goes!
