Certificates

Note

This page is a work in progress.

Errors relating to certificates occur when the Paperless-ngx instance is configured using a self-signed SSL certificate. Such a certificate is not automatically trusted by the operating system, which then returns an error when the app tries to connect to the server.

Possible solutions are:

  1. Using a trusted SSL certificate, for example from Let's Encrypt.
  2. Adding the self-signed certificate or the signing certificate authority certificate to the device's trust store at the system level.
