Synology: Install Paperless NGX With Office Files Support

Synology Install Paperless NGX With Office Files Support

Paperless-ngx is a document management system that transforms your physical documents into a searchable online archive so you can keep, well, less paper. After my article on How to Install Paperless NGX on Your Synology NAS, many people have contacted me asking for an even more comprehensive guide so that office files such as .docx could also be uploaded. In this step by step guide I will show you how to install Paperless-ngx with Office files support on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Paperless-ngx 2.5.4 release.

  • STEP 16

Go back to STEP 1 or you will deal with karma 🙂.

  • STEP 17

Now open your browser and type in your HTTPS/SSL certificate like this https://paperlessngx.yourname.synology.me that you have previously created at STEP 6. In my case it’s https://paperlessngx.mariushosting.synology.me If everything goes right, you will see the Paperless-NGX Login page. Type in your own admin Username and Password that you have previously created at STEP 13 then click Sign in. Follow the instructions in the image below. ⚠️Warning: if you get an error message that says Username and/or password incorrect, this means your NAS is slow and didn’t create the superadmin user. You need to wait 2-3 minutes longer and try to log in again. Don’t rush to change the password or reinstall everything from scratch, just wait.

🆘TROUBLESHOOTING

If you encounter issues by using this container, make sure to check out the Common Docker issues article.

🔥Troubleshoot: If you get the “Error while converting document to PDF: 503 Server Error: Service Unavailable for url: http://gotenberg:3000/forms/libreoffice/convert” – This is usually due to the server being “down” for scheduled maintenance or due to a heavy traffic load that prevents it from properly serving all incoming requests. You need to wait until the server is back up again. Also, the issue can be related to the fact that you are trying to access PaperlessNGX locally instead of via Reverse Proxy. Websocket at STEP 7 is mandatory.

🔥Troubleshoot: In case you get the following error message: Error occurred while consuming document invoice.pdf: DigitalSignatureError: Input PDF has a digital signature. OCR would alter the document, invalidating the signature, just add the following Environment variable in the compose at STEP 13:

PAPERLESS_OCR_USER_ARGS: '{"invalidate_digital_signatures": true}'

Add it after:

PAPERLESS_CSRF_TRUSTED_ORIGINS: https://paperlessngx.yourname.synology.me

It should look like this:

PAPERLESS_CSRF_TRUSTED_ORIGINS: https://paperlessngx.yourname.synology.me
PAPERLESS_OCR_USER_ARGS: '{"invalidate_digital_signatures": true}'

💡Suggestion: You can also install Stirling-PDF to better manage your documents.
💡Suggestion: You can also install DocuSeal that provides secure and efficient digital document signing and processing.
