timeout during connect

[GRRedWings]

I'm using Python 3.11 to create a connection to NATS running in docker. I am trying to do TLS (and eventually mTLS), but I'm having issues with timeout on connect.

If I write a small standalone script that starts a thread and does all of the connections inside of the thread, things seem to work fine. But if I try to do this same thing in a larger Python application I get timeout errors

[1] 2024/02/27 12:35:59.326756 [ERR] 192.168.0.1:46584 - cid:948 - TLS handshake error: read tcp 192.168.0.3:4222->192.168.0.1:46584: i/o timeout
[1] 2024/02/27 12:35:59.326790 [ERR] 192.168.0.1:46584 - cid:948 - TLS handshake timeout

I assume I'm doing something different or wrong, but it's really unclear to me. Is there a way to set the timeout on the connection?

Here is how I am creating my connection

        self.host = host
        self.port = port
        self.connectionUrl = 'tls://{}:{}'.format(host, port)
        self.certificate = '[Full Path to Root CA]'

        ssl_ctx = ssl.create_default_context(purpose=ssl.Purpose.SERVER_AUTH)
        ssl_ctx.load_verify_locations(self.certificate)

          self.natsConnection = await nats.connect(servers=self.connectionUrl, tls=ssl_ctx, tls_hostname=self.host,
                                                     error_cb=self.error_cb,
                                                     disconnected_cb=self.disconnected_cb,
                                                     closed_cb=self.closed_cb,
                                                     reconnected_cb=self.reconnected_cb)
