URLError: <urlopen error [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661)>

I get the error in the title

I have python 2.7.14 and OpenSSL 1.0.2k 26 Jan 2017

ctx = ssl.SSLContext(ssl.PROTOCOL_TLS) #Itried all the other protocols
ctx.check_hostname = False #fails with or without these 2 lines
ctx.verify_mode = ssl.CERT_NONE
resp = urllib2.urlopen(url, context=ctx).read()

Update: This is the url (sensitive data replaced with ..) https://www.upwork.com/api/hr/v2/teams/../users.json?oauth_consumer_key=..&oauth_nonce=..&oauth_signature_method=HMAC-SHA1&oauth_timestamp=..&oauth_token=..&oauth_version=1.0&tz=gmt&oauth_signature=..

All keys and tokens work because I also use them on a javscript platform and they work perfectly there. Also simply pasting the link in browser works. But in python I have no idea how to debug this. Anyone can please help ? Thank you, deeply appreciated

There is no ssl.PROTOCOL_TLS. There are for example ssl.PROTOCOL_TLSv1 which does not work and there is ssl.PROTOCOL_TLSv1_2 which does work for me. Even better use ssl.create_default_context().
