Flow: Out of Retries

The flow server is not responding (3 retries remaining): -The flow server is not responding (2 retries remaining): \The flow server is not responding (1 retry remaining): |The flow server is not responding (0 retries remaining): /
Out of retries, exiting!

I used flow to check one file only these moment, and it's..

// @flow
export default (store:Object) => {
  // watch lang
  store.watch(
    state => state.system.lang,
    (lang:string) => {
      window._V_.$i18n.locale = lang
      window._V_.moment.locale(lang)
    }, {
      deep: true
    }
  )
}

and I run flow check, 0 error(s) found.

Same issue with 0.83.0. Just goes in loops.

Facing the same with version 0.74.0

Why is this closed? What's the resolution?
I simply get this:

 (1386)-> yarn flow
yarn run v1.13.0
$ /home/ash/projects/myproj/web-app/node_modules/.bin/flow
The flow server is not responding (0 retries remaining): /
Out of retries, exiting!
error Command failed with exit code 7.

Also, npx flow check gives Found 0 errors

Edit: Found the solution. Thought maybe a flow server was already running, and it was. So just had to stop it: flow stop from the project root dir for which it was initially started. Then yarn flow works fine.
