Issue : Sign in to Google is not working.

I am new to Google Cloud tools and facing problem at very first step where I need to sign in to Google account.
When I hit "Sign in to Google" It opened the login process in external browser(Chrome), After login and giving permission, It redirects to localhost:RANDOM_PORT/Callback?code=xxxxxx

This URL doesn't exist and showing "This site can’t be reached", standard google chrome page ,

In eclipse, Showing processing dialog window with Cancel option.

Not sure why callback redirection is to a Random localhost port ?

Additional information:
I tried with Safari and result is same.

Can you clarify if what you see is the literal string "RANDOM_PORT"? If so, that's certainly a bug. (However, it is correct that it should be some random localhost port.)

[sanc-enovate]

It is some random localhost port like 60456, 54329 and so on

[chanseokoh]

I see. At least it is correct that it redirects to a random localhost port. When the login browser launches, our CT4E plugin also listens from the port locally to receive the code value. Let me check what could go wrong.

[chanseokoh]

The fact that you see actual random port numbers very likely suggests that the local web server is up and running (in-process, and not as a separate process).

I suspect your browser is blocked from accessing "http://localhost", perhaps due to your proxy settings. Can you update your browser proxy settings so that localhost addresses bypass the proxy?

[sanc-enovate]

I doubt about proxy, my node JS apps run smoothly on different port, web server works fine Any other thought?

[briandealwis]

Are you behind a firewall or anti-virus?

Could you check your <workspace>/.metadata/.log?

[chanseokoh]

First, let's check if the local web server is listening, and then try to connect to the local web server from other clients than browsers, such as wget in the terminal.

Let Eclipse be the only Java process. netstat -tlnp will give you listening TCP ports with process names. I recommend restarting Eclipse before doing this. Normally, there shouldn't be any Java process.

$ netstat -tlnp

Then, click on the login button in Eclipse. When the "Sign in to Google" dialog pops up, check which port is open. There will be one Java process:

So, you now know there is a Java process listening on port 41237. Try

$ wget 127.0.0.1:41237
$ wget localhost:41237

If it returns 404, then at least we know the server is running and it's the browser problem.

I sometimes see Eclipse listen on some port on its own, so I recommend you check netstat multiple times by clicking on the login button and cancelling the "Sign in to Google" dialog.

[chanseokoh]

Also, hitting /Callback?error=whatever will return 200 or 302, so this is the sure thing to know if the server is the right one. When returning 200 or 302 with this URL, the server dies, and the "Sign in to Google" dialog in Eclipse will disappear.

Netstat stuff did the trick, Here are the steps that help to resolve the issue (Steps for Mac):- 1. Click on "sign in to google" 2. Run below command on terminal sudo lsof -i -n -P | grep TCP 3. Check the IP and port with program name eclipse 4. When the callback url returned on browser, simply replace `localhost` with the IP address noted in step 3 and press Enter 5. We are good. *What is the root cause* : Google sign-in process run a local web server on 192.168.*.*:45678 in place of (127.0.0.1/localhost):45678 .

Seems like this can happen when there are multiple localhost interfaces. We need to let Jetty return the actual host here:
