Issue with Opening PDF from URL in docViewer.OpenDocument() - Error Message Included

Hi Team,

I’m working with DocuNot MVC Core and using the DocuNot.NETStandard (25.10.0) version. I’m trying to open a PDF document hosted at a URL using the docViewer.OpenDocument() method, but I’m running into an error. Here’s the code I’m using:

var pathToFile = “https://www.antennahouse.com/hubfs/xsl-fo-sample/pdf/basic-link-1.pdf”;
docViewer.OpenDocument(pathToFile, config, documentOptions);

However, I’m getting the following error:
"Unable to open document. Error: {“success”:false,“message”:"Physical file does not exist or has no read access, https://www.rd.usda.gov/sites/default/files/pdf-sample_0.pdf"}"

Can anyone help me figure out what’s going wrong? I suspect it might have something to do with how URLs are handled in DocuNot.

Any suggestions on how I can resolve this? Is there something special I need to do when opening a document from a URL?

Thanks in advance for your help!

Thank you for your detailed post and for sharing your code snippet.

We have tried to replicate the issue on our side using the same approach with a remote PDF URL, but unfortunately, we were not able to reproduce the error.

To help us investigate this more accurately, could you please share a small sample project that reproduces this behavior? A minimal MVC Core project with the same configuration where the issue occurs would be perfect.

Once we have the sample, we’ll be happy to analyze it and provide you with a precise solution.
