Unable to Start Kestrel

If Kameleo is not starting, you might see the following lines in your logs or console:

[17:03:45] [INF] 3 local profile(s) loaded.
[17:03:46] [INF] Authentication started with email user@example.com.
[17:03:49] [INF] Authentication successful, waiting for commands.
[17:03:52] [FTL] Unable to start Kestrel.
[17:03:52] [FTL] Application startup failed.
[17:03:53] [INF] Application terminated

Cause: This error occurs because another instance of Kameleo (or another application) is already using the same port 5050.

Solution:

  • Make sure no other Kameleo instances are running. Check the Task Manager and close any additional instances before starting the application.
  • See if no other application is running on port 5050. (Try restarting your your computer to eliminate the chances)
