Regarding "done" before "release" -- that's actually ok, the question is just if all buffers were released apparently. This is how a run looks like where things worked fine: 2025-10-24 13:23:44,378 - INFO - Server port is not found this time, retry after 0.5 seconds 2025-10-24 13:23:44,882 - INFO - HTTP Server is
