Ok, I figured out what was wrong. It was kind of foolish of me. I had two problems with my code. My first mistake was when specifying the ssl_version I put in TLSv1 when it should have been ssl.PROTOCOL_TLSv1. The second mistake was that I wasn't referencing the wrapped socket, instead I was calling the original socket that I have created. The below code seemed to work for me.
Copyimport socket
import ssl
# SET VARIABLES
packet, reply = "<packet>SOME_DATA</packet>", ""
HOST, PORT = 'XX.XX.XX.XX', 4434
# CREATE SOCKET
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(10)
# WRAP SOCKET
wrappedSocket = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_TLSv1, ciphers="ADH-AES256-SHA")
# CONNECT AND PRINT REPLY
wrappedSocket.connect((HOST, PORT))
wrappedSocket.send(packet)
print wrappedSocket.recv(1280)
# CLOSE SOCKET CONNECTION
wrappedSocket.close()
Hope this can help somebody!

You shouldn't be setting PROTOCOL_TLSv1 (or TLSv1). This restricts the connection to TLS v1.0 only. Instead you want PROTOCOL_TLS (or the deprecated PROTOCOL_SSLv23) that supports all versions supported by the library.
You're using an anonymous cipher, because for some reason you think you don't need a certificate or key. This means that there is no authentication of the server and that you're vulnerable to a man in the middle attack. Unless you really know what you're doing, I suggest you don't use anonymous ciphers (like ADH-AES256-SHA).

Solving SSL Errors in Python Requests - Esri Community
February 12, 2025 - So, knowing that ArcGIS Pro had already been reinstalled and it didn't help, the installer must not have replaced this file, it must have just checked it and moved on or appended data to it? Not sure there. Either way, I renamed the old one and put a copy of the cert found on the other machine after a new install and BAM! My machine could now perform a web request through Python without throwing an SSL error.

If you are on Windows and use anaconda this worked for me:
I tried a lot of other solutions which did not work (Environment PATH Variable changes ...)
The problem can be caused by DLLs in the Windows\System32 folder (e.g. libcrypto-1_1-x64.dll or libssl-1_1-x64.dll or others) placed there by other software.
The fix was installing openSSL from https://slproweb.com/products/Win32OpenSSL.html which replaces the dlls by more recent versions.
