Duplicated host information in newsletter url

[#1]

Hi

We've followed the instructions under https://helpx.adobe.com/experience-manager/6-3/sites/authoring/using/campaign.html to test the integration of Adobe Campaign 6.1.1 with AEM 6.3.

We get stuck at the point, where we would like to add the Newsletter form AEM to the delivery in Campaign. When we click the Synchronize button in the delivery, the available email templates are visible as you can see here:

But when we select one and click on ok, we got the following exception:

2018-03-13 09:44:53.005+01 00001380 00001B00   2 error log Value '6300http:' is not a valid integer (32 bit) (iRc=-2010)
2018-03-13 09:44:53.005+01 00001380 00001B00   2 error log The port defined by string 'http://aem-demo-author.internal-test.com:6300http://aem-demo-author.internal-test.com/libs/mcm/campa...' of URL '6300http:' has no valid format. (iRc=-2010)
2018-03-13 09:44:53.005+01 00001380 00001B00   2 error log Network error (socket(), errno=10022 : an invalid argument was supplied.) (iRc=-61)

Does anyone know why we got duplicated host information in this url?

After adding the instance port information to the 'Day CQ Link Externalizier' under /system/console/configMgr/com.day.cq.commons.impl.ExternalizerImpl, the synchronization works as expected.
