SO Annoying!

So for whatever reason Blogger won't let me sign into my "name" to comment on other peoples blogs. But yet I can sign in and update mine and read all of yours. All it does is keeps redirecting me to login to post my comments, every single time. It never tells me my information is wrong, just doesn't sign me in. So I have been patiently trying to comment on all your blogs, it just won't let me. If anyone knows how to fix this issue, please let me know!
