https 301 errors and SEO

This question is related to a few tools that are returning errors and that I am not sure what to do about them, if anything.

At: http://andylangton.co.uk/online-tools/http-status-analyser

if I analyze http://drchrono.com

I get "Status code is 301. Status is Moved Permanently to https://drchrono.com/."

This makes sense but if I then analyze that address, https://drchrono.com/ I get the same error.

Do I need to fix this?

How?

Does this affect SEO?

I think it's just an error in the tool you are using, if you test this http://www.seoconsultants.com/tools/headers.asp you get correct OK 200 answer
