Problems with Python 2.7.12

Hello, I was trying to use your script in my webfaction account. When I ran the command

python letsacme.py --no-chain --account-key account.key --csr domain.csr --acme-dir challenges > signed.crt

I got the error

ssl.CertificateError: hostname 'USERNAME.webfactional.com' doesn't match either of '*.webfaction.com', 'webfaction.com'

I think it is an error with SNI. When I ran it using Python 3.3.6 it worked like a charm

Are you using wildcard domain in CSR?

No. I was trying to use it for my webfaction account. It is USERNAME.webfactional.com
