The issue you are facing:
I am using Community Document Server bundled with NC and Onlyoffice plugin. I can view or edit .docx or .xslx or .odt files with no problems (so the server seems to be working and configuration paths must be correct, right?), but every time I try to view a PDF, i get “Connection is lost” error message.
If i uncheck PDF handling in OnlyOffice settings, I can open it properly (standard pdf.js viewer comes up). I was trying to test watermarking feature on PDFs as well (which itself is not related because disabling watermarks does not resolve the issue).
Steps to replicate it:
- Upload any PDF file
- Click on it
- Choose “open in OnlyOffice”

What looks really strange to me is these calls to undefined path.
I tried to disable redis/APCu caching, checked all the seemingly related threads regarding document server paths or x2t execute permissions - the issue persists. I am completely out of ideas.
