# Troubleshooting

If you're having issues getting a Perigee application to start or load properly, check the below items:

## License check

The license check run's immediately on application startup, and if a valid license is not detected, it will immediately shut down the application. 

1. Make sure you have a valid license, and your trial period is not expired
2. Make sure you're copying that license file to the output directory, or it is installed on the server.

## Serilog configuration

If a Serilog sink is configured to startup on a remote source (like a database), Please verify that it has an open connection and there are no firewalls preventing Serilog from initializing.
