When I try to authorize a new Dev Hub using the Force.com IDE 2 in Windows 10, I get a stacktrace after a couple of seconds:

com.salesforce.tools.ide.cli.api.SfdxApiException: Cannot start the oauth redirect server on port Error.

I have a suspicion: A timeout. I have noticed several times that the force.com cli is running very slow, to execute

sfdx force:org:list

it takes my system roughly 12 seconds. To execute a plain

sfdx

it takes my system roughly 2.5 seconds. More info:

  • cmd "node --version" outputs v6.10.0
  • My sfdx cli is the neweset version as of today

Did anyone face the same issue?

    workaround: Kill the running node.js process when it happens. Then you have a new try. The running process seems to be blocking a port. – Mario Hammer Jul 17 '17 at 11:12

This troubleshooting tip from the Salesforce DX Developer Guide worked for me on MacOS.

It also has instructions for Windows (which I cannot test).

It's basically the same as @Mario Hammer's comment -- kill whatever other process is using the port the authorization needs
