Can't open online archive in IM after upgrade to DX UIM 23.4: "proxy login"

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

After upgrading to DX UIM 23.4, it is no longer possible to access the online / web Nimsoft archive through the Infrastructure Manager (IM).

When accessing the archive node, it loads and then prompts a "proxy login"

Our primary hub machine (where the IM is installed) connects to the internet via a proxy. Before the upgrade (DX UIM 20.4CU7) opening the archive was possible. 

While this issue occurs, It is still possible to connect to the archive via the Admiconsole (Configure the Admin Console to access the Web Archive using a Proxy Server)

Environment

DX UIM 23.4.*

Cause

Security Enhancement. In DX UIM 23.4 the connection to the archive via the IM was upgraded from HTTP to WinHTTP (more secure). The proxy settings must allow WinHTTP through the proxy. Not having this enabled, will cause the described issue. Proxy setting only set for HTTP will not allow proxy connection established using WinHTTP.

Resolution

1) --Run the following command to check the proxy settings and verify if WinHTTP is configured.

netsh winhttp show proxy 

2) --if winHTTP is not set, run the following command with the proxy, target IP

netsh winhttp set proxy <##.##.###.##:###>

3) --if winHTTP is not set, and HTTP is set already on source "ie" (internet Explorer) run the following command: 

netsh winhttp import proxy source=ie
