Unable to connect to Gmail

Upon imap.connect() I get:

Uncaught Error: self signed certificate
...
  code: 'DEPTH_ZERO_SELF_SIGNED_CERT',
  source: 'socket',
  domainEmitter: Connection {
    _events: [Object: null prototype] { ready: [Function], end: [Function] },
    _eventsCount: 2,
    _maxListeners: undefined,
    _config: {
      localAddress: undefined,
      socket: undefined,
      socketTimeout: 0,
      host: 'imap.gmail.com',
      port: 993,
      tls: true,
      tlsOptions: undefined,
      autotls: undefined,
      user: <my gmail id>,
      password: <my google app password>,
      xoauth: undefined,
      xoauth2: <my access token>,
      connTimeout: 10000,
      authTimeout: 5000,
      keepalive: true
    },
...

My IMAP is enabled; I have 2FA; I tried an App Password only (didn’t work); I tried adding the xoauth2 token.

Anyone can help? Thanks!

For everyone who still gets this error, you need to add tlsOptions: {servername: "<imap server/host parameter>"} to the Imap() object.

This solved the issue for me: https://stackoverflow.com/a/60126034/1166371

Add tlsOptions: { rejectUnauthorized: false }
