- Implement the reconnect and republish with async service calls. bug fixes: - subscription Ids should start from a random number - the keep alive interval calculation is too short, adding +1 for the timeout - on BadSessionIdInvalid recreate session immediately - on a restarted server with new certificate, also reload endpoints when BadCertificateInvalid is returned
