"Another user has a console session open to this virtual machine" or black screen using the web console

  • 1.  "Another user has a console session open to this virtual machine" or black screen using the web console

    Posted May 30, 2024 05:46 AM

    When I need to use the web console from ESXi (version 8.0.2 build-23825572 and 7.0.3 build-23794027) I periodically got either the yellow ribbon

    "Another user has a console session open to this virtual machine"

    or/and a complete "black screen" with a play logo on it (like when the VM is turned off).

    I can only see on the web console the following errors:

    Uncaught DOMException: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.

    Having the exact same issue, image with profile HPE-Custom-AddOn_802.0.0.11.6.0-5 (Hewlett Packard Enterprise). Very very very annoying. Happens each minute, almost impossible to do my work.
