SSL Error "unexpected message"

Question

When I tested some Python code for different scenarios, I received the following error for the correct port, URL, username, and password:

SSL23_GET_SERVER_HELLO:sslv3 alert unexpected message

I got the exact same error and traceback when I used a bogus username, and also when I used the correct username but the wrong password. Could it be expecting SSL v3, and the version that is installed is older? Just a guess. I didn't see anything in the Python code that set the SSL version number.

Please post a minimal reproducible example so that people can examine your code and see if there is something wrong there. — Ken Y-N

It sounds like you are using Python2.7 and a 3rd party library like requests. If this is the case you should try this pip install request[security] most packages that I have run into that have to deal with this will have the [security] version. — SudoKid

For what it's worth, here are the last several lines of the traceback. The Python code referenced is in GitHub at github.com/kennethreitz/requests — user3429841

You can use SSLAdapter to set the SSL and TLS versions.

I was getting a similar error and it was caused by the server using TLS 1.3, but I only have TLS 1.2 installed. So I had to do the following:

from requests_toolbelt import SSLAdapter import ssl import requests session = requests.Session() session.mount('https://', SSLAdapter(ssl.PROTOCOL_TLSv1_2)) session.get(myurl)

If you can reach the server with a browser, you can check the SSL and TLS version by clicking on the lock or shield symbol next to the url.
