Sorry…Your username and password do not match

Hi guys,

I can login to Gmail.com on any desktop/mobile browser however whenever I try to add a Google Account on my phone, I get this error:
“ Sorry…Your username and password do not match. Please try again. (To recover your account information, go to http://google.co.uk/accounts on your computer.)"

I have tried changing the password but its still the same. I know its not a password issue as I can login to google.com on my desktop and laptop.

I also went to this site and tried to add a Google account but it did not work.

Tried setting up a different Google ID and it worked right away. So it looks like there has to be some issue with my Google ID.

I have no idea how it happened as it was working fine until I reset my phone.

Any ideas?

Thanks,
Dinesh
