To be honest, it's not too much different from the Houdini example in the docs at the moment, which is why I'm not sure what's going on. Let me know if something sticks out.

    Unfortunately there is no reliable way of detecting the machine from the browser, not in a way that can be re-created from python. I've made a small plugin (see code below) that detects if there are multiple instances of Connect running for a user and pops up a message. If this functionality makes sense and you like it, we may bundle the plugin in Connect. import logging import socket import functools from QtExt import QtWidgets, QtCore import ftrack_api import ftrack_connect.util import ftrack_connect.ui.application logger = logging.getLogger( 'multiple-instances-plugin' ) def open_warning_dialog(message): '''Open warning window.''' parent = None for item in QtCore.QCoreApplication.instance().topLevelWidgets(): if isinstance(item, ftrack_connect.ui.application.Application): parent = item dialog = QtWidgets.QMessageBox(parent=parent) dialog.setText(message) dialog.setIcon(QtWidgets.QMessageBox.Critical) dialog.exec_() def handle_reply(event): '''Handle reply event if someone else is already running Connect.''' logger.warning('Someone else is already running connect: {0}'.format(event)) ftrack_connect.util.invoke_in_main_thread( open_warning_dialog, u'ftrack Connect is already running on machine: {0}'.format( event['data']['machine'] ) ) def callback(event): '''Handle start of another connect.''' logger.warning('Someone just started ftrack Connect: {0}'.format(event)) ftrack_connect.util.invoke_in_main_thread( functools.partial( open_warning_dialog, u'Connect just opened on machine: {0}'.format( event['data']['machine'] ) ) ) return {'machine': socket.gethostname()} def register(session, **kw): '''Register hooks.''' logger.info( 'Register detection of multiple Connect instances' ) # Validate that session is an instance of ftrack_api.session.Session. If # not, assume that register is being called from an old or incompatible API # and return without doing anything. if not isinstance(session, ftrack_api.Session): logger.debug( 'Not subscribing plugin as passed argument {0!r} is not an ' 'Session instance.'.format(session) ) return session.event_hub.subscribe( 'topic=studio.ftrack-connect.start and source.id != "{0}" and ' 'data.username = "{1}"'.format( session.event_hub.id, session._api_user ), callback ) session.event_hub.publish( ftrack_api.event.base.Event( topic='studio.ftrack-connect.start', data={ 'username': session._api_user, 'machine': socket.gethostname() } ), on_reply=handle_reply ) To use it create a folder detect-multi-instance/hook/ inside the ftrack connectp plugins folder, and add the code in a plugin.py (don't forget the hook/ folder). Restart Connect for the plugin to source. This simple example could be extended with the ability to "quit" other instances of ftrack Connect.
