The issue you are facing:
After upgrading to 13.0.1, PDFs no longer display:
Some users mentioned such an issue here before. As far as I know the issue was solved by a full reload of the NC page (CTRL + R). Seemed to be a caching issue.
Could you try if that is the case for you as well?
If that doesn’t help and the logs contain no information, then the browser console output might be useful.
We are having the same issue. Except we have 13.0.5. PDF viewer 1.2.1. PDF’s stopped loading used the Ctrl-R and it is now working.
So is this just a fluke with PDF viewer?
User is continuing to have issues viewing PDF’s even after refresh?
