# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
