There has been a change in Lotus Notes Traveler 8.5.2 and 8.5.3 in the way the Traveler servlet URL is set within the Traveler servlet page.
If using Traveler 184.108.40.206 or later (also known as Traveler Upgrade Pack 1), use the instructions for updating the External URL here.
If using Traveler 8.5.2 or other 8.5.3 releases, use the steps below.
In Traveler, the URL should be specified using the External Server URL field, which can be found in the Server document on the Lotus Traveler tab, as shown in the example below:
This field should specify the complete path to the Traveler servlet, including http:// or https://, any port numbers if non-default values are in use, and should end in /servlet/traveler.
The URL is case-sensitive and must be entered in all lower-case.
This URL is used to set the Traveler servlet URL that is downloaded by a user from the Traveler servlet page and is set in the device's configuration as the URL through which to perform all Traveler transactions and data synchronization. The URL is also used by other Traveler components, such as the Lotus Notes Traveler Companion application for reading encrypted mail on Apple devices.
This value should be a URL that Traveler users can always access, whether on an internal network or the internet, and should not change. If there is a reverse proxy in use, the URL should be set using this reverse proxy name. If there is a DNS name or IP that is used to route external traffic to the Traveler server from the internet, the URL should be set using this DNS name or IP address.
After making a change to the External Server URL in the server document, restart the Traveler task.
The External Server URL field will only be present if the server's address book is at the 8.5.2 template level or above. If the field is not present in the server document because the address book is on an older template version, the External Server URL can be set in notes.ini with this parameter:
If NTS_EXTERNAL_URL is added to or changed in notes.ini, restart the Domino server to make the change effective.
: The NTS_EXTERNAL_URL parameter in notes.ini will take precedence over the External Server URL field in the Server document. If NTS_EXTERNAL_URL was added to notes.ini while using Traveler version 8.5.1, ensure that the value is correct as described in this article, as this parameter's usage has changed in version 8.5.2. Problems may occur due to an incorrect URL setting that were not experienced in version 8.5.1. The best option is to remove this value from the notes.ini and use the value in the server doc as outlined above.
