Heavyai-connector

[hatdio]

I am using heavyai-connector (https://github.com/heavyai/heavyai-connector) and its example.html in my installed Heavydb server (Free edition).

While I am connecting (port 6278) and I get also correct response in "get_tables" method,
when I call a query I get either "NS_ERROR_NET_RESET" in XHR request or - if use port 6273 - "502 Bad getaway" and message ""remote http://localhost:6278 unreachable, could not forward: EOF" (while again I connect with success)

Any ideas?
