The X11Web container uses a KasmVNC which does not support dynamic socket allocation
The KasmVNC container tries to use a custom KasmVNC build with support for dynamic socket allocation, but it has a bug in handling websockets.
For this reason, the container rollback using the Xkasmvnc binary from a KasmVNC version which does not support dynamic socket allocation.
- TODO: build KasmVNC "latest" with the support for dynamic socket allocation and ensure that the build has the websocket bug fixed.
