* fix: gently log the port on which the realtime service listens without this, the service remains completely silent (e.g. in overmind) and it is hard to tell if it is even running * Revert "fix: gently log the port on which the realtime service listens" This reverts commit 14a21989c6767520d8e1b9d46cc9f58a45768563. * refactor(socketio): explicitly listen on port --------- Co-authored-by: Ankush Menat <ankush@frappe.io>
