Right now I am having this problem with hundreds of Windows 10 machines across many customers. Not all machines are having this issue at those customers.
On the computers having this problem, I am unable to load pdf files on dynamically generated websites. Below is an example url to a pdf.
In Edge and Internet Explorer, a URL like this will trigger a download notice. If I save or save as, it will want to save as a txt file. If I rename the extension after saving to PDF it will not open in Acrobot.
If I go to a url like this https://example.website.com/test.pdf
Edge will attempt to load it multiple times then fail with the following error message
This page is having a problem loading.
However, in Internet Explorer the pdf opens just fine as long as it's a definitive path to a .pdf file.
I have tried the following
Deleting temporary internet files and caches.
Restore/Reset Internet advanced options
Added URL/Reset Trusted sites
Uninstalled/Repair latest version of Adobe Acrobat
Disabled Windows Firewall and Antivirus (temporarily to test)
Firefox and Chrome work fine but cannot be used in these environments due to Browser standardization around Edge/IE in locally developed or government applications.
Anyone else run into this recently or have any ideas on what to do to resolve this issue?
Update: This is now occurring with any file such as exe, doc, docx etc. Not just PDF. A reboot temporarily fixes it but starts happening within a few minutes to an hour after reboot.
