This page applies only to self-hosted Presenton.

​
Application does not open

Confirm the container is running, the configured host port is free, and traffic is published to container port 80. Review container logs for startup failures.

​
Presentations or settings disappeared

Confirm the replacement container mounts the same persistent host directory to /app_data. A container without that mount starts with empty application data.

​
Provider cannot connect

  • Verify the provider URL, model, and credentials.
  • Test the provider outside Presenton when possible.
  • Use a hostname reachable from inside the container.
  • Confirm the required model is installed and running.

​
Authentication callback fails

Confirm all required callback ports are published and reachable from the browser performing authentication. Check that another process is not already using the configured port.

​
Before upgrading

Back up /app_data, pin the new image tag, review release notes, and test providers, templates, API integrations, editing, and export before replacing production.
