      In configuration of SSH device checked "Use SSH port forwarding for debugging".

      I created docker device (aarch64) which has gdb and other dev tools. It's used to build and debug app for RPi.

      When gdb under docker is trying to connect "localhost:10000" while it should connect to "host.docker.internal:10000". Eventually it times out with error message.

       

      I created a quick workaround patch, which resolves this issue.
