Thanks. That was quick.
Just wondering how I can add that to my endpoint_description create serverfromstring.
Or will I have to drop that.
Let me take a look.

Hope this helps,

I'm using endpoint_description with a tac file to start up a server.
But I need to disable tls 1.0 and 1.1.
I was hoping to find a parameter I could pass in to make the system only recognise 1.2 and 1.3. But could not find anything that would do that. I thought sslmethod would be what I wanted but that is limited to :
Must be one of: "SSLv23_METHOD", "SSLv2_METHOD", "SSLv3_METHOD", "TLSv1_METHOD". If I choose TLSv1_METHOD, TLS1.0 and 1.1 are still enabled and QUALYS complains and downgrades the rating to B In the end I found _defaultMinimumTLSVersion in _sslverify.py.
I set this to TLSVersion.TLSv1_2 and that seemed to do the trick.
But I don't think I should be doing that. I think I've missed some obvious place where I can pass in a value to change this.
Anyone know where I should be looking.
Thanks for any info
