GraphQL not working, works on different computer

[mithradantor]

Hi,

on my laptop its working perfectly, on PC I cant get it to work. Files are 1:1 copies, everything works except GraphQL.

When I go to Graphiql I get this error in red text:

graphQLFetcher@http://localhost:8000/graphiql:84:24 value@https://cdnjs.cloudflare.com/ajax/libs/graphiql/0.11.3/graphiql.min.js:1:45916 value@https://cdnjs.cloudflare.com/ajax/libs/graphiql/0.11.3/graphiql.min.js:1:39247 [6]</a</e.prototype.notifyAll@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:12:7723 close@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:18192 closeAll@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:15:9577 perform@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:15:9075 s@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:10988 perform@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:15:8995 batchedUpdates@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:4148 i@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:23073 _renderNewRootComponent@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:12243 _renderSubtreeIntoContainer@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:13228 render@https://cdnjs.cloudflare.com/ajax/libs/react/15.5.4/react-dom.min.js:14:13355 @http://localhost:8000/graphiql:104:13

Does anyone know how to fix this? and when I copy the entire project 1:1 how come it works on my laptop but not on my PC?
