How to fix 403 & Redirect Errors

Hey, I’m getting URL returned 403 error and redirect errors on Google Console. When I “Test Live URL” it all comes back green and says I can request indexing. When I press TEST ROBOTS.TXT BLOCKING I try to add a property but it says “sc-domain://, but it’s not in your account”

Not sure if doing the test is the solution or if i need to do something else?

Can anyone let me know if there’s something else to do?
