MIB Management Shows "Retry" Instead of "Download" in the SolarWinds Platform Web Console

This article describes why the MIBs Management page in the SolarWinds Platform displays a Retry button instead of the expected Download button, and provides steps to resolve it. The root cause is typically a firewall blocking direct outbound HTTPS access to the SolarWinds endpoints required for MIB database status checks. Resolutions cover firewall/proxy adjustments, certificate trust remediation, and manual offline MIB database installation.

Overview

When navigating to Settings > All Settings > MIBs Management, the page displays a Retry button instead of the expected Download button. The page may also show the message:

Failed to determine MIBs database status

Clicking Retry either does nothing or continues to show the same message.

Cause

The MIBs Management page requires direct outbound HTTPS access to the following external endpoints to determine the current database status and present the Download option. If any of these URLs are blocked by a firewall or routed through an HTTP proxy, the page cannot determine the MIB database status and displays Retry instead.

Required endpoints:

* https://customerportal.solarwinds.com
* https://api.solarwinds.com
* https://downloads.solarwinds.com/solarwinds/Release/MIB-Database/MIBsVersion.json

Note: MIB Management does not support proxy-based access. The SolarWinds server must communicate directly with the above endpoints.

Resolution

Perform the following steps on the main polling engine and any additional polling engines in the environment.

Resolution 1: Allow Outbound Firewall Access

1. From the SolarWinds server, open a browser and confirm that all three URLs listed under Cause are accessible.

2. If any URL is blocked, work with your network/security team to allow direct outbound HTTPS (TCP 443) to api.solarwinds.com and downloads.solarwinds.com on the firewall.

3. If an HTTP proxy is configured for the SolarWinds server, bypass it for this traffic. MIB Management requires a direct connection and cannot function through a proxy.

4. After adjusting firewall or proxy settings, navigate back to Settings > All Settings > MIBs Management and click Retry.

Resolution 2: For Offline Environment

If the SolarWinds server does not have internet access, the Retry behavior is expected. Download the MIB database manually from the Customer Portal:

1. On a machine with internet access, log in to the SolarWinds Customer Portal using your SolarWinds Customer ID and password.

2. Navigate to Downloads > MIB Database.

3. Select the appropriate installer for your platform version:

* SolarWinds Platform 2025.2 or later and click Download As MSI V2 (MIBsv2.msi)
* SolarWinds Platform 2025.1.1 and earlier then click Download As MSI (MIBs.msi)

4. Transfer the file to the SolarWinds server.
5. Run the MSI on all deployed polling engines, the main polling server, HA backup server, and any additional polling engines.
