Hey,
i am using GraphQL Playground HTML in version 1.2.0 (absinthe/graphql-playground). I was wondering why the playground is connecting (by default) to a websocket at wss://subscriptions.graph.cool. Could you please explain why this is necessary?

@johannestroeger My apologies for that weird behavior in the playground. That endpoint you can see there was used for testing, if a websocket endpoint is valid. I just removed it and replaced it with the correct value (which is the subscriptionsEndpoint), it will be released today or tomorrow.
Excellent, glad to hear it!
Fixed in the latest version. Please let us know if you still have that issue, then we reopen it!
