Qlik Explorer for Developers - WebSocketConnectionNotAccepted and http error code 500
I'm trying to run the Qlik Explorer for Developers, but when I try to connect to the playground, I get the error message displayed in the image.
I do get this same error when I try to run the Qlik BotNet demo.
Does anyone bump into this while trying to run Qlik Explorer? I'm trying to test my connection to the playground and, afterwards, to my own Qlik Sense Cloud Server for the BotNet. Seems like maybe can be due to some configuration on my machine.
