URL links are getting corrupted by Acrobat Reader.

We create password protected PDFs which contain links to external URLs.
These links work fine when we view the generated PDFs in chrome and firefox.
But the links are getting corrupted by Acrobat Reader.
One or more characters are getting corrupted (e.g "https://mywebiste.com/1234567" is trying to link to "https://mywebiste.com/123:567" or "https://my?ebiste.com/1234567")
