error code 1006

[mokcoo]

I'm using graphql ws for subscription, I have an apollo gatway as the backend and using react on front end, this error does not happen in the local environment, but whenever I publish it online, which is using cpolar to expose it in the public, this websocket is generating the next problem.

Close code 1006 means that something out of graphql-ws control has went sideways.

There are a few things you can check:

• Your production environment does not handle WebSockets properly
• Your production environment does not support the GraphQL over WebSocket protocol and is abruptly terminating the connection
• Your production environment has a proxy and the proxy is not handling WebSockets properly
