I am having trouble signing in to a pdf document. The first two fields in the pdf are username and password which are required to look up information from a particular source. When I click the login button I get the following error:
Can anyone help please? I'm using Adobe Acrobat Reader DC 2020.009.20063 on a Macbook.
It is really hard to comment in this situation. It seems the form is trying to connect to a particular address. You need to check with your IT if that address is whitelisted on your machine. Also, with the designer of the form if that address still holds true. Also Acrobat>Preferences>Security(enhanced), try whitelisting the address if you know that in advance.
If you can share the file with us we will try to take a look.
