When accessing a Google document through Canvas, one of four things will happen: you will be able to access the file, be asked to login to google, receive a connection error  or receive an access denied message.

If Google documents are used in class they will be shared with your wisc.edu Google account and not your personal.  If you are having issues accessing the file it is because you are not currently logged into Google with your netid@wisc.edu account.

If when clicking on the link in Canvas for a Google document you receive the error accounts.google.com refused to connect that means you are either not logged into google on that browser or you are logged into an account that doesn't have access to the document.  Click on the document name in white found in the header and circled in blue below.  This will open the document in a new window/tab.

When it open in the new window/tab you will either see a screen to login to Google or that the account you are logged in with doesn't have access.

If you see the Google Sign in screen, login with your netid@wisc.edu.  It will then take you to the UW login screen.  Put in your netid and password and should then be taken to the file.

If you see the access denied screen click on the Google account you are signed in as, illustrated below with the blue circle.  This will take you to a new screen.  If your @wisc.edu account is an option to select, select that.  If yours @wisc.edu account isn't there click on Sign in to another account and sign in with your netid@wisc.edu, like the step above.
