Auto fill from CRA not working

[Marjo362]

I have tried different browsers, clearing cache, etc and nothing is working.  I would really like to file my taxes.  I keep getting this error message:

Error—ERR.021

We cannot proceed with your request.

 for help.

When contacting us, provide this message number. Have your individual tax return on hand and be prepared to answer additional questions.

Error 21 relates to your Netfile access code. It can be found just under the date on your Notice of Assessment. It changes every year.  Check that to ensure you have the correct access code.
