Hi, I looked into this and found the error you're seeing is an issue in
the novaconsole client, not nova itself.

I have opened the following PR to update the client:

"""
websockify dropped support for text frames awhile back [1][2], possibly
as of version 0.9.0 [3]. Attempts to send text frames to a sufficiently
new websockify server result in the following error returned:

Unsupported: Text frames are not supported

and then the server closes the connection.

This changes the client to call Webocket.send_binary() [4] instead of
Websocket.send() in order to send binary data rather than text.

websockify has (always?) supported receiving binary data so this should
be backward compatible with older versions.

Closes #4

[1] novnc/websockify#365
[2] novnc/websockify@8eb5cb0
[3] novnc/websockify@8a69762
[4] https://websocket-client.readthedocs.io/en/latest/core.html#websocket._core.WebSocket.send_binary
"""

https://github.com/larsks/novaconsole/pull/5

Feel free to try the above change locally and see if it solves your
issue.

I'm closing this as Invalid for nova.

** Changed in: nova
