Converged, Hyperconverged Infrastructure & Virtualization

Recently came across an issue in our Production environment that VRA Agent status was showing as Down in one of our Sites.

The screenshot is shown as below:

On investigating, we checked the vSphereAgent.log file which is present on the server where this VRA agent was installed and configured. (In our case it was one one of the IWS (IAAS Web Server) Node)

The location of this log file is at C:\Program Files (x86)\VMware\vCAC\Agents\<VRA_Agent_Name>\logs\

In this log, you can find multiple lines with an error:

This exception was caught:
System.Web.Services.Protocols.SoapException: vCenter Error: Cannot complete login due to an incorrect user name or password.

if this is the case, check the LDAPS Certificate to your Domain Controllers of the domain you have added on the vCenter server Web UI.

Even though it doesn’t show you the certificate expiry in this UI, you can check the certificate status by logging into vcenter SSH and executing the following command:

openssl s_client -connect adds01.corp.test.local:636 -showcerts

Replace the Domain Controller hostname with your domain controller hostname after the -connect in the above command to get the valid cert from the domain controller.

In our case, we found that the cert on the domain controller has been recently renewed and we had to input the new cert to the Identity Source in the vcenter web UI.

Once the new cert is installed, you can login into your VRA Default Tenant (VRA 7.6), go to Infrastructure -> Endpoints -> Endpoints and go to your vcenter and click on edit and then re-validate the service account password (Test the connection) and once it is successful, the VRA Agent will come back UP.

Hope this article helps you if you see your VRA agents as down and can’t find anything else missing or even restarting the vra agent service doesn’t change the status.
