    Connecting to a physical display, version 7.10, remote Ubuntu 18 machine, connection either via Windows 10 or Ubuntu 22 on Lenovo Thinkpad.

    From the client side error log:

    ProxySession/ProxySession: ERROR! Session failure in stage ‘StageWaitingProxyVersion’.

    Error: Session negotiation failure.

    ProxySession/ProxySession: ERROR! We possibly provided a wrong version

    ProxySession/ProxySession: ERROR! or an invalid session authentication cookie.

    Error: Connection closed by the remote peer.

    Session: Session terminated at Sat Nov 05 03:57:41 2022.

    Encryptor/Encryptor: WARNING! Destroying pending buffer with 88 bytes.

    ClientSession: Exiting from the client transport loop.

    ClientSession: The transport closed with reset ‘1’ error ‘5’.

    ClientSession: Session at 0x00000000034cc500 failed.

    ClientSession: Failing reason is ‘The connection with the server was lost.

     

    Error is 5: Input/output error.’.

    This then repeats itself. What is the issue here?

    thanks for your help
