[Bug] Cross-Origin Request Blocked

[SnowyTheVampire]

Bug Report

Hi, this is more personalized to a fork of ever-demand than the origin, so I apologize in advance. I did reach out on discord for the best tangible means of asking for assistance. I've tried to replicate ever-demand mostly for educational purposes, with the hope to find a tangible ecommerce solution at the same time.

The first issue I experienced was with MongoDB localhost, that I solved by changing the http:// links from localhost to 127.0.0.1, due to it wanting to handshake on ipv6 (::1) instead of ipv4...

But the second issue which I am currently stuck on is an error thrown in browser, during yarn run:server and run:shopweb, stating: "Cross-Origin Request Blocked: The Same Origin policy disallows reading the remote resource at http;//****. (Reason: CORS header 'Access-Control-Allow-Origin' missing). Status code: 200."

🕗 Version & Regression Information

• This is a bug in azure live development browser window
• This is the development fork of ever-demand
• I tried creating a build of the master branch, but had several bugs that were overtly difficult with my limited knowledge and ultimately went back to the development branch.

🙁 Actual behavior

After fresh installing Node + everything that's bundle with it (npm, python, Microsoft tools, etc), globally re-installing yarn latest, installing MongoDB, running 'yarn install' within the relevant origin folder to download dependencies, running 'yarn build:all' and launching the servers with 'yarn run:server' and 'yarn run:shopweb', I am greeted with working environments. (I had better luck with 'yarn install', than trying to use 'yarn bootstrap', 'yarn lerna bootstrap' or npm installing lerna globally).

However, when i connect to localhost:4200, which both 'yarn run:shopweb' and 'yarn run:admin' are wanting to load onto (shopweb not running on 3000 for some reason?), I am greeted with the Cross-Origin Request Blocked error. This is a repeating error that is preventing then sending and receiving of information.

I'm experiencing the same issue, has there been any progress on this?

@SnowyTheVampire @djriffle are you running all in http, without https? And all runs on 127.0.0.1? From screenshot, it's not clear what URL you try to open in browser, only clear that it tries to connect to socket.io server running on port 5500 on 127.0.0.1... So it means that issues are to connect from admin / web shop to socket.io host?
