I deployed a simple apollo grapqhl server to heroku (http://filex-database.herokuapp.com) but when I try to access the playground on my main machine the playground doesn't load and gets stuck at Loading Screen. The playground loads perfectly when I run the server locally.
The same heroku server works fine if I access it from my laptop though (and even another browser in my machine).
Maybe it's something to do with Chrome. But I don´t know where to start debugging.
