Hyperlinks to FAQ page not opening from exported PDF (Acrobat Reader)

Hi everyone,

I'm running into an issue with external web links inside a PDF document viewed in Adobe Acrobat Reader (latest desktop version on Windows 11).

We compiled our onboarding documentation from InDesign/Word and included a direct link to our web resource:

https://onyxgrowthlabs.com/faq/

When clicking this link inside the document:

• The cursor changes to the hand icon as expected.

• However, when clicked, either nothing happens or Acrobat hangs for a couple of seconds without launching the default browser (Chrome/Edge).

• Other standard links (like google.com) appear to open fine, but this specific URL structure or protocol doesn't trigger the browser prompt.

I've already checked:

1. Preferences > Trust Manager > Internet Access from PDF Files (it is set to allow web access).

2. Tried running Acrobat Reader as Administrator.

Is there a specific security or URL formatting requirement in Acrobat Reader that blocks certain secure (HTTPS) subdirectories or causes external links to silently fail? Any suggestions on what settings or document properties I should inspect?

Thanks in advance.
