Chrome update, new error: XMLHttpRequest cannot load

[IAMtheIAM]

Everything was fine, until I restarted chrome for an update. Now I get

XMLHttpRequest cannot load http://localhost:4000/sockjs-node/info?t=1463600087201. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'http://localhost:5000' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.
client?59d4:70 [WDS] Disconnected!

I do not have access-control-allow-origin specified in my code. What happened?

Not sure why it happened, but to fix it I just did clean:install and it works now. Something got busted in my node_modules.

Very weird, but the same thing just happened again after another chrome update. XMPHttpRequest CORS not allowed wildcard. This time it was a chrome extension Allow-Control-Allow-Origin: * version 1.0.3 causing a problem. Disabling the extension fixed it.
