I have confirmed I have no proxy configured anywhere on my home network (I would have been surprised if there was). I have checked using Internet Explorer> Internet options>Connections>LAN Settings. I have also checked with commandline netsh winhttp show proxy, and it clearly says " Direct access (no proxy server)." Yet I'm still unable to connect. The thing is, when I try to connect with default port 443, the system bombs out completely with the below error on trying to start the datafeed:

File "C:\Users\Blessing\OneDrive\Symphony\PythonBDK\bots\orders-bot\env\lib\site-packages\aiohttp\connector.py", line 990, in wrapcreateconnection
    raise ClientConnectorSSLError(req.connectionkey, exc) from exc
aiohttp.clientexceptions.ClientConnectorSSLError: Cannot connect to host develop2.symphony.com:443 ssl:default [Cannot create a client socket with a PROTOCOLTLSSERVER context (ssl.c:801)]

However, if I put port 8433, the system repeatedly tries to connect, but gets the below error:
