Hi @<1817731756720132096:profile|WickedWhale51> ! ClearML is tolerant to network failures. Anyway, if you wish the upload the offline data periodically, you could zip the offline mode folder and import it:

# make sure the state of the offline data is saved
Task.current_task()._edit()
# create zip file
offline_folder = Task.current_task().get_offline_mode_folder()
zip_file = offline_folder.as_posix() + ".zip"
with ZipFile(zip_file, "w", allowZip64=True, compression=ZIP_DEFLATED) as zf:
    for filename in offline_folder.rglob("*"):
        if filename.is_file():
            relative_file_name = filename.relative_to(offline_folder).as_posix()
            zf.write(filename.as_posix(), arcname=relative_file_name)
Task.import_offline_session(zip_file, task_holding_reports="PASS_VALID_ID_TO_AVOID_DUPLICATES")

Also, note the task_holding_reports argument
