Trouble getting authentication to work on new SOAP project

Hi all,

I am setting up a brand new instance of SOAP UI. I've used the tool before but only modified data elements in projects that were already set up, so basically I'm a pretty basic beginner. I am trying to send a test request/response to a specific URL with a WSDL and am getting the 401.1 error. I have access to the page. I set my authentication type to Basic and typed in the user name and password for the website (which works). I've looked at set up documentation but I am still doing something wrong. The endpoint URL works, the user name and password works on the UI, and I have permissions on the website to login via a webservice. I've set the authentication type to Basic and tried the pre-emptive global authorization. Nothing works. Help?

Thank you!
