VNC is Getting disconnected in aerokube moon

i deployed moon aerokube on my k8s cluster, i enabled vnc option on my code, but i am unable to see the test execution on the VNC in question, and i got the following error :

enter image description here

I would like to know why ?

in addtion, i will give the logs of each container of the pod related to the session lanched by my program:

07/10/2022 11:58:39 ------------------ USEFUL INFORMATION ------------------
07/10/2022 11:58:39 X DAMAGE available on display, using it for polling hints.
07/10/2022 11:58:39   To disable this behavior use: '-noxdamage'
07/10/2022 11:58:39 
07/10/2022 11:58:39   Most compositing window managers like 'compiz' or 'beryl'
07/10/2022 11:58:39   cause X DAMAGE to fail, and so you may not see any screen
07/10/2022 11:58:39   updates via VNC.  Either disable 'compiz' (recommended) or
07/10/2022 11:58:39   supply the x11vnc '-noxdamage' command line option.
07/10/2022 11:58:39 
07/10/2022 11:58:39 Wireframing: -wireframe mode is in effect for window moves.
07/10/2022 11:58:39   If this yields undesired behavior (poor response, painting
07/10/2022 11:58:39   errors, etc) it may be disabled:
07/10/2022 11:58:39    - use '-nowf' to disable wireframing completely.
07/10/2022 11:58:39    - use '-nowcr' to disable the Copy Rectangle after the
07/10/2022 11:58:39      moved window is released in the new position.
07/10/2022 11:58:39   Also see the -help entry for tuning parameters.
07/10/2022 11:58:39   You can press 3 Alt_L's (Left "Alt" key) in a row to 
07/10/2022 11:58:39   repaint the screen, also see the -fixscreen option for
07/10/2022 11:58:39   periodic repaints.
07/10/2022 11:58:39 
07/10/2022 11:58:39 XFIXES available on display, resetting cursor mode
07/10/2022 11:58:39   to: '-cursor most'.
07/10/2022 11:58:39   to disable this behavior use: '-cursor arrow'
07/10/2022 11:58:39   or '-noxfixes'.
07/10/2022 11:58:39 using XFIXES for cursor drawing.
07/10/2022 11:58:39 GrabServer control via XTEST.
07/10/2022 11:58:39 
07/10/2022 11:58:39 Scroll Detection: -scrollcopyrect mode is in effect to
07/10/2022 11:58:39   use RECORD extension to try to detect scrolling windows
07/10/2022 11:58:39   (induced by either user keystroke or mouse input).
07/10/2022 11:58:39   If this yields undesired behavior (poor response, painting
07/10/2022 11:58:39   errors, etc) it may be disabled via: '-noscr'
07/10/2022 11:58:39   Also see the -help entry for tuning parameters.
07/10/2022 11:58:39   You can press 3 Alt_L's (Left "Alt" key) in a row to 
07/10/2022 11:58:39   repaint the screen, also see the -fixscreen option for
07/10/2022 11:58:39   periodic repaints.
07/10/2022 11:58:39 
07/10/2022 11:58:39 XKEYBOARD: number of keysyms per keycode 7 is greater
07/10/2022 11:58:39   than 4 and 51 keysyms are mapped above 4.
07/10/2022 11:58:39   Automatically switching to -xkb mode.
07/10/2022 11:58:39   If this makes the key mapping worse you can
07/10/2022 11:58:39   disable it with the "-noxkb" option.
07/10/2022 11:58:39   Also, remember "-remap DEAD" for accenting characters.
07/10/2022 11:58:39
