Socket timed out without establishing a connection within 3100 ms

[ala85]

A NodeJs application, running on my machine, localhost, has the following

const { HttpsProxyAgent } = require('https-proxy-agent');
const { NodeHttpHandler } = require('@smithy/node-http-handler');

...
const proxyAgent = new HttpsProxyAgent(process.env.PROXY);
    const requestHandler = new NodeHttpHandler({
      connectionTimeout: 30001,
      requestTimeout: 60001,
      socketAcquisitionWarningTimeout: 60001,
      httpAgent: proxyAgent,
      httpsAgent: proxyAgent,
    });

..
const credentials = fromTemporaryCredentials({
      params: assumeRoleParams,
      credentials: Credentials,
      region: process.env.AWS_DEFAULT_REGION,
    });


return new SQSClient(
      {
        region: process.env.AWS_DEFAULT_REGION,
        credentials,
        requestHandler,
      },
    );

..
const command = new ReceiveMessageCommand({
    QueueUrl: queueUrl,
    MaxNumberOfMessages: 10,
    WaitTimeSeconds: 20, // Long polling
    AttributeNames: ['All'],
    MessageAttributeNames: ['All'],
  });

const { Messages } = await client.send(command);

Regardless of any combinations of parameters, the socket timeout still seems to be defaulting to 3100ms:

Socket timed out without establishing a connection within 3100 ms

Am I missing something? SocketTimeout is derecated in favour of requestTimeout, but issue persists.
