Start Errors

After creating the container image of your application, it is deployed in our infrastructure, the following errors may happend if your application is not configured correctly.

If something wrong happens, the first reflex to have is to look at the logs of your app, in most of the case, all the information you need is displayed here.

Boot Timeout

When started on our servers, your application has 60 seconds to bind the port defined by the environment variable PORT. After this delay, we consider that your application is not able to boot and this error happens.

Common causes

  • The server is not listening on the port defined by the environment variable PORT. Then your application is running correctly but it is not reachable.

Crash of the application

When your application starts, it may stops unexpectedly for various reasons related to your project.

Common causes

  • Syntax error and import error in your code. Make sure that your project is working correctly locally before deploying it on our platform. If it doesn’t, it won’t be better here.
  • The database link is badly configured. If you are using our builtin database addons, we create a environment variable with a name following this scheme: SCALINGO_{DB_TYPE}_URL So your application has to use this value or you can rename it to fit your needs.
