Find out what exactly goes wrong

To identify the cause of the problem, refer to the log file for the detailed error message and full stack trace. If seeking community help, providing these details initially can save a lot of time.

Locate the log file

Go to the directory where you click Crynux Node.exe, there is a sub directory with name data, and inside data folder there is a folder with name logs, all the log files can be found inside.

There are several log files inside the logs folder. The content of each file is described below:

  • crynux-server.log: Node manager related logs.

  • crynux-worker.log: Task executor related logs.

  • crynux_worker_inference.log: Task execution logs.

  • crynux_worker_prefetch.log: Model downloading logs.

  • main.log: GUI related logs. Not available on Docker versions.

Most of the error messages could be identified in the first two log files: crynux-server.log and crynux-worker.log.

Locate the error message

Open the log file in a text editor. Navigate to the time where you encountered the error, and find the lines with [ERROR], which is usually the error message. And there will be a stack trace around the error message. If you are asking for help, remember to provide the full stack trace from the first line to the last.

Here is an example of a log file with error message and the stack trace:
