Troubleshooting

This guide walk you though the steps required to troubleshoot LibreTime.

FAQ​

I cannot login the interface "Oops! Something went wrong!"​

You might be accessing the interface from an invalid URL. Make sure that the URL in your browser and the one set in your configuration file in [general.public_url] are the same.

Make sure to check the legacy logs at /var/log/libretime/legacy.log.

Logs​

The first place to search for details on potential errors are the log files.

The /var/log/syslog file contains most of the system logs combined. This log file may contain information that the application logger wasn't able to log, such as early startup errors. You can follow the logs using:

sudo tail -n 100 -f "/var/log/syslog"
# Filter the logs
sudo tail -n 100 -f "/var/log/syslog" | egrep 'libretime|nginx|php.*-fpm'

On a common setup, to access LibreTime specific logs you should search for the following files:

  • The /var/log/libretime/analyzer.log file contains logs from the analyzer,
  • The /var/log/libretime/api.log file contains logs from the api,
  • The /var/log/libretime/legacy.log file contains logs from the legacy app,
  • The /var/log/libretime/liquidsoap.log file contains logs from liquidsoap,
  • The /var/log/libretime/playout.log file contains logs from playout.
  • The /var/log/libretime/worker.log file contains logs from the worker.

For some LibreTime services, you can set a higher log level using the LIBRETIME_LOG_LEVEL environment variable, or by running the service by hand and using a command line flag:

sudo -u libretime libretime-analyzer --config /etc/libretime/config.yml --log-level debug

The /var/log/nginx/libretime.error.log file contains logs from the web server.

Services status​

The next reflex is to verify whether the services are running.

In the web interface, go to Settings > Status to see the state of the services.

Or directly from a terminal:

sudo systemctl --all --plain | egrep 'libretime|nginx|php.*-fpm'

If a service isn't running, you should search for details using the tool running those services. On a common setup, you should use the systemd service status:

sudo systemctl status libretime-worker
note

Be sure to replace the service name with the problematic one.

Test the stream inputs​

To test or debug your input streams, you can use the tools/test-stream-input.py script to send a test sound to your stream inputs.

To test the main input stream, you can run the following command:

./tools/test-stream-input.py \
    --host radio.example.org \
    --port 8001 \
    --mount main \
    --user source \
    --password hackme

# Or using the --url option
./tools/test-stream-input.py --url source:hackme@radio.example.org:8001/main

If you are hitting HTTP error 401 Unauthorized on the main input stream, make sure that you have configured a user and password in the Settings > Streams settings page.

If you are connected but don't hear anything streaming, make sure that the main input stream is connected and enabled. In addition, to automatically turn on/off the stream on connect/disconnect you can configure the input stream auto switch in the Settings > Streams settings page.
