Question Cannot link to PDF - server error 510

[the-ninth]

Hi,

In a Text Editor element, I am trying to create a link to a PDF, which I have uploaded to a local directory of my server. This is the same domain under which Wordpress is running, but I created the documents folder manually via FTP).

I can add the link but when updating the page, I get an error 510. I tried different link forms, full URL, relative URL, all of them lead to the same error. If I link an HTML page under the same directory it works fine, only linking PDF leads to the 510 error. Also just opening the PDF link in a browser works fine, so I know the link is correct.

Screenshots are attached.

What could cause this?

Thanks for your support!

Regards, Robert

Any ideas anyone?

It seems all other kind of files work. Just linked a ".docx" file and it works just fine. Only if I link a ".pdf" file I get this server error 510.
