Mitmweb.exe works fine, but mitmdump.exe doesn't

Hello,

I starts mitmweb or mitmdump on windows 10 and see all https requests from android emulator. but mitmweb works very well, mitmdump does not.

I tryed different combinations of options.

mitmdump -s test.py
mitmdump
mitmdump -s test.py --cert *=my_cert.pem

I see the same result: output with many erros of TLS

192.168.1.54:58823: CONNECT www.google.com:443
<< Cannot establish TLS with www.google.com:443 (sni: None): TlsException(‘Cannot validate certificate hostname without SNI’,)

And my android application crashes too, but works fine then mitmweb.exe is started and all output lines of https requests seem as ok.
