@vkholodov can you try with this guide? https://blog.postman.com/how-to-use-graphql-subscriptions/

the screenshot makes me thing it's doing a POST request and not a WS

(maybe we should do a better error in that case)

After your question I tried graphiql web app and it works. Trying to figure out what's wrong with postman request.

Maybe we can work on improving the error message in the web view here. Especially with regard to SSE/Multipart Subscriptions, indicating that a wrong / unsupported method is used will be a valuable addition.
