i was not able to use my account

Hi There

Check this previous post for some tips: https://repost.aws/questions/QUwnXvvsQyRzut3QE3ct3qOg/account-is-currently-blocked-when-trying-to-create-ec-2-instance

it is possible that your account is limited to use certain region only as free tiers ( mainly US East (N. Virginia), US East (Ohio), US West (Oregon)) You can validate by trying to create the EC2 in those regions. if you need more regions, you will have to contact aws-verification@amazon.com and explain why you need other regions.
