CORS (Allow-Cross-Origin) Error. How to fix?!

You need to change all configs and replace all localhost with your ip number or domain name.

How it's work.

Check file: /cezerin2/src/index.js This code:

// CORS headers
var allowedOrigins = security.getAccessControlAllowOrigin()
var origin = req.headers.origin
if (allowedOrigins === "*") {
  res.setHeader("Access-Control-Allow-Origin", allowedOrigins)
} else {
  if (allowedOrigins.indexOf(origin) > -1) {
    res.setHeader("Access-Control-Allow-Origin", origin)
  }
}

And this file: /cezerin2/src/lib/security.js

const getAccessControlAllowOrigin = () => {
  return [settings.storeBaseUrl, settings.adminBaseURL] || "*"
}

storeBaseUrl and adminBaseURL settings located in your config /cezerin2/config/server.js

Quitting the store and the api in the wrong way can lead to this error. The solution in linux is killing the process that using the port that gives you the error:

to obtain the PID of the process:

lsof -t -i:3000

to kill the PID:

kill -9 PID

or more simply in one command:

kill -9 $(lsof -t -i:3001)
