Summary

This is an error I received in the mitmproxy event log while running a python script to connect to our server over HTTPS. The script uses httplib2 (we need to support old Python versions :/).

Issue details
  • Python 2.7.10 (using pyenv)
  • OS X 10.11
  • ssl module compiled against OpenSSL v0.9.8zg
  • HTTPS connection fails with the following error from the event log in mitmproxy
Error
127.0.0.1:56425: ProtocolException("Error in HTTP connection: HttpSyntaxException('Bad HTTP request line: \\x80F\\x01\\x03\\x01\\x00-\\x00\\x00\\x00\\x10\\x00\\x009\\x00\\x008\\x00\\x005\\x00\\x00\\x16\\x00\\x00\\x13\\x00\\x00',)",)
Workaround
  • If I swap in an ssl module compiled with OpenSSL 1.0.2d, the request succeeds without issue.

Not sure if this is user error, an issue with that version of OpenSSL, or a bug in mitmproxy. I haven't opened an Issue for it because I'm not entirely convinced where the issue lies yet.
