Warning: The Least Cost Routing has failed X time(s) in a row


To ensure the ship remains informed about any unexpected occurrences that could impact critical operations, the Connection Suite is designed to dispatch designated warning email messages to the ship's Postmaster, typically the primary email account.

These emails are generated promptly upon the triggering of specific criteria, irrespective of the temporary or persistent nature of the highlighted issue.

Before initiating any action, it is advisable to personally evaluate whether the task referenced in the email is currently functioning as expected. If it is, this indicates that the failure was transient, and no further action is necessary.



This automated notification is triggered when the primary communication carrier onboard fails to establish a connection with the Dualog shore servers for email exchanges. Typically, this issue arises due to inadequate coverage or the presence of connectivity issues between the communication carrier onboard and our shore servers.

If your ship's Postmaster account consistently receives these system notifications, please note that it is not feasible to halt their transmission, as they are activated whenever data transmission issues occur via communication equipment. However, you have the option to extend the warning delay or designate an alternative account as the ship's Postmaster.


Given that poorly performing communication equipment is the primary cause of this notification, it is advisable for vessel IT personnel and the airtime provider to investigate this issue in the first instance.

To minimize the frequency of these warnings or to alter the destination account for these notifications, you have the option to extend the warning delay or modify the ship's Postmaster account.


The warning delay denotes the number of failed connections required before generating this warning in the Postmaster account's inbox.

By default, this setting is at 0. However, considering that most vessels connect at intervals of 20 minutes or less, this default setting might result in an inundation of warnings in the inbox during extended outages lasting a few hours. Therefore, it's advisable to adjust this delay to a higher value.

You can configure the warning delay both on the Dualog Portal and the admin panel of the ship Connection Suite version 3.10 and above. (Look for the setting under "Cloud Connection Settings" on the communication equipment page.)

  1. On Dualog Apps portal, navigate to Connection Suite -> CS Ship Setup -> select vessel -> Communication -> scroll down and expand 'Cloud connection settings'.


  • In ship Connection Suite 3.10, the steps will be identical after accessing the admin panel and opening up the configuration page of 'Communication Setup'.




The Postmaster account is the account that will receive automated notifications related to the Dualog, and this can only be changed on the Dualog Portal.

The setting will be found under email -> settings -> onboard server settings, as the below gif illustrates.
