Hello @inodb!

I've researched this problem and found that it can be due to Google's Document Viewer. This issue is widely known and has been discussed on Stack Overflow (https://stackoverflow.com/questions/35298724/google-docs-viewer-occasionally-failing-to-load-content-in-iframe).

I believe the solution to this problem is to continuously try to load the document from Google using intervals.

If this solution seems acceptable, I can attempt to fix this issue.

Thank you!
