To start I know that TLSv1.0 is super old and should not be used, but I need to connect to some really old local hardware that isn't supporting anything else atm

I've tried several ways. The above code is mostly ripped from similar issues posted here in the past but python3 ssl no longer supports TLSv1 so it throws an unsupported protocol error. I added the "import urllib3.contrib.pyopenssl" to try and force it to use pyOpenSSL instead per this urllib3 documentation. The current error with this code is
load_verify_locations() takes from 2 to 3 positional arguments but 4 were given
I know this is from the verify part of urllib3 context and I need to fix the context for pyOpenSSL but I've been stuck here trying to fix the context.
