Using TLS Connection to hub-cloud.browserstack.com

[daniel-gerne-pag]

Thank you for the handy snibbets.
Because of security policies in my company we use https for every outgoing connection. By default protractor connects to http://hub-cloud.browserstack.com/wd/hub.
I tried:
'seleniumAddress': 'https://hub-cloud.browserstack.com/wd/hub',
But I get SSL errors:
EPROTO write EPROTO 1192:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\deps\openssl\openssl\ssl\record\ssl3_record.c:252

How can I use TLS for connection with browserstack?
