Background
I want to add a self-signed SSL key to a small http python server based on Tornado framework. I've followed this manual to generate the SSL keys and this question to configure Tornado.
The problem
Once the server receive a request it throws:
SSLError: [Errno 336445449] _ssl.c:369: error:140DC009:SSL routines:SSL_CTX_use_certificate_chain_file:PEM lib
The questions
What is causing the above error? How can I fix it?
