Absinthe GraphQL query document not supplied on one laptop, works perfectly fine on another

I’ve had this weird issue where a 2017 macbook pro’s browsers (connecting to remote servers or running the server locally) would not initiate the graphQL playground at all, and return the “No query documents supplied” error when accessing the endpoint.

However, the same servers ran locally (or accessing the same remote ones) on another older macbook pro, a windows laptop, and a windows desktop behave perfectly fine.

I don’t think I need to brew install graphQL as it is the ide that is being installed.

All 4 devices were using the same wifi connection as well.

Is there anyone who ran into this issue and managed to solve it / find the cause of it?
