Yes, by no connection I meant that the remote server isn't there to connect to. The code is from an aws lambda so any call can be the 1st call to this particular lambda instance & occasionally the remote server isn't reachable.

After a bit more testing it doesn't hang - it just does nothing. In my lambda test it does eventually time out after a couple of minutes but just tries again despite the server being unreachable but that coudl be the nodejs express servr retrying. I cannot find a way for it to time out after a few seconds and give an error or other event/return value I can use to log/return the correct error. The lambda times out after a configured period and just returns 'server error' which can return to anything that takes too long but that isn't helpfull for monitoring/debugging.

>             Project: TinkerPop
>          Issue Type: Bug
>          Components: javascript
>    Affects Versions: 3.4.8
>            Reporter: Philip
>            Priority: Major
>
> constructor...
>      const authenticator = new PlainTextSaslAuthenticator(userName,dbData.password)
>      this.dc = new DriverRemoteConnection(connectionStrArray.join(''), \{ authenticator })
>     this.graph = new Graph()
>   
>  function code...
>      const g = this.graph.traversal().withRemote(this.dc)
>        let count = await g.V().count().next()
>        console.log(count)
>   
>  This works great with a connection but with no connection it failed with a crash error in 3.3.8 - not ideal  but was manageable as code is always run as a dynamic object per. In 3.4.8 when there is no connection it never resolves or times out so it just hangs. 
> I haven't found a work around as yet
