Websockets errors: ELB issue or symptom of something else?

We are using Dremio AWS edition. We have it behind an ELB that forwards port 22 -> 22 (TCP), 443 -> 9047 (HTTPS), and 32010 -> 32010 (TCP). The UI mostly works, except for stuff that depends on websockets. So, you can’t see the results of a query in real time, for instance. We get “Error during WebSocket handshake: Unexpected response code: 405”. My theory has been that it doesn’t work with ELB and requires an ALB instead. But in one of my environments, staging, this doesn’t seem to be an issue…
