Timeout occurred error when accessing Provider Event Notifications in VMware Cloud Director Availability

Products

• VMware Cloud Director

Issue/Introduction

In VMware Cloud Director Availability (VCDA), users may experience a "Timeout has occurred" error when attempting to access the Provider Event Notifications section under Events and Notifications.

Analysis via browser developer tools reveals that the API call GET /config/notifications/provider takes approximately 30 seconds to complete, which exceeds the hardcoded UI timeout threshold.

This behavior is typically observed in environments with a high count of Organizations and system users.

Environment

VMware Cloud Director Availability 4.7.3.1

Cause

VCDA does not have a local SMTP or email configuration, forcing the application to dynamically iterate through all Organizations and system-level users in VMware Cloud Director to retrieve roles, email addresses, and server settings each time the page is accessed.

Resolution

To resolve this issue, configure local SMTP settings within VCDA to override the dynamic lookup process:

1. Log in to the VMware Cloud Director Availability Management Interface as an administrator.

2. In the left pane, navigate to Settings.

3. Under the General section, locate Provider event notifications.

4. Configure a Custom SMTP Server and provide the necessary authentication details.

5. Define the Notification Email settings (Sender and Recipient addresses) specifically for VCDA.

6. Click Save.

7. Navigate back to Events and Notifications > Provider Event Notifications to verify the page loads successfully without a timeout.
