AFR and "the request is blocked"

Has anyone experienced this? Receiving “The request is blocked” after connecting to CRA with AFR from T1. Log in to CRA is successful, SIN requested is display, next, then the error message.

UPDATE: disabled all browser extensions and is okay now. I’ll systematically enable extensions and post again if i determine the exact problem. Thank you!

Yes. I have had similar problems. I normally have to log in twice before I can download the AFR.
