OpenSSL handshake fails to some Mongo Atlas clusters with Python 3.10 (the only difference is the python version, we have cross-tested this excessively) with the following error message:

pymongo.errors.ServerSelectionTimeoutError: SSL handshake failed: <redacted>.mongodb.net:27017: EOF occurred in violation of protocol (_ssl.c:997), Timeout: 30s, Topology Description: <TopologyDescription id: 618e3379ad71635cdecdd729, topology_type: Single, servers: [<ServerDescription ('<redacted>.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('SSL handshake failed: <redacted>:27017: EOF occurred in violation of protocol (_ssl.c:997)')>]>
