Hello,

I am encountering an issue with noVNC when trying to connect to an iDRAC8 server. While the connection to an iDRAC9 server works flawlessly, the iDRAC8 server connection results in a successful WebSocket connection but only displays a black screen with a cursor.

**Details of the Issue:**

- VNC server is enabled on both iDRAC8 and iDRAC9, with identical configurations.
- iDRAC9 displays the console data correctly.
- iDRAC8 establishes the WebSocket connection without errors but fails to display console data, showing only a black screen with a cursor.
- The VNC port configured in the database was initially mismatched (5901 instead of iDRAC’s 5900) but has been corrected without resolving the issue.
- WebSocket message patterns differ between iDRAC8 and iDRAC9, with iDRAC8 showing unusual binary messages when the black screen is present.
- There are no apparent errors in the browser console or network logs.

**Attempted Debugging Steps:**

- Ensuring both iDRAC versions are up-to-date.
- Verifying noVNC’s configurations for any potential mismatches with iDRAC8’s expectations.
- Checking for any differences in initialization sequences or data encoding.

**Assistance Required:**

I am looking for guidance on how to troubleshoot this issue further, particularly:
- Insights on potential compatibility issues between noVNC and iDRAC8.
- Any known issues or fixes related to noVNC and iDRAC8 connections.

Any help or suggestions from the community would be greatly appreciated.

Thank you.

These embedded VNC servers are unfortunately often buggy, so I'm not
entirely surprised there are issues. :/

Does it work with other VNC clients? E.g. TigerVNC?

Do you have to configure other VNC clients in some specific way to make
things work?

That is interesting. If possible, see if you could try websockifys
recording feature. If you could share a recording with us, we could do
some debugging on our end.
