KB Number:
000001050

Symptoms:
Reasons for a ZCA installation to fail:

1] Error is received when running the Zerto Virtual Replication installer on an EC2 instance after inputting the 'Access Key ID' and 'Secret Access Key'. It is confirmed that the 'Access Key ID' and 'Secret Access Key' are correct.

2] Install logs will show the following error:

Amazon.Runtime.Internal.HttpErrorResponseException: The remote server returned an error: 401) Unauthorized. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized.

Cause:
1] The EC2 instance where Zerto is being installed is in the incorrect AWS region.

2] The ZCA EC2 instance was not granted external internet access.

Solution:

1] Try logging into 'AWS Management Console' with your 'Access Key ID' and 'Secret Access Key' .  A successful or unsuccessful login will confirm whether each ID is correct.

2] At the "Connectivity and AWS Authentication" section of the Zerto Virtual Replication installer, double check that you are inputting the correct 'Access Key ID' and 'Secret Access Key'.  If you are certain the 'Access Key ID' and 'Secret Access Key' are correct, please proceed to step 3 below.

3] Open the 'AWS Management Console' and confirm that the correct region is selected.  From the navigation bar, view the options in the region selector.

If the incorrect region is selected please change it by selecting the correct region.

5] Create a new EC2 instance or migrate the existing EC2 instance to the new region.  To migrate the existing EC2 instance please see the below steps:

Migrating an EC2 Instance to a New AWS Region:

5.1] In the instances tab of the 'AWS Management Console', shutdown the EC2 instance where Zerto is being installed
5.2] Right-click the EC2 instance and select 'Image' -> 'Create Image' to create an AMI from the instance
5.3] Click on the 'AMI's' tab, right-click on the new AMI and select 'Launch Instance'
5.4] In the new instance settings, choose the correct availability zone

6] After a new EC2 instance has been created, power on the instance and copy over the Zerto Virtual Replication Installer to the Windows Desktop.  If the EC2 was migrated to the new region, start the EC2 instance and run the Zerto Virtual Replication Installer.

7] Fill in all the necessary parameters during the installation.

8] Confirm that the ZCA has been allowed external internet access.
