Tonia,
%20 is just a uri encoding for space, something browsers do automatically. From the 2 urls, I can see the databasenode=\PROGNOSISIR and databasenode=\WBR-SRV-PROG001 so it is looking for a different node for database.
As Stefan said, if you can share the screenshot of the error (if its red dot, the hover over message), we can help identify what the issue is.
