Issue/Introduction

Unable to configure the MDM server as the server is not showing up in the server tab of the "MDM Windows Workspace" as seen here:
 
 
Troubleshooting Steps:
  • User informed us that they are unable to configure the MDM server as the server is not showing in the server tab of the "MDM Windows Workspace"
  • Users uninstall and reinstalled the MDM plug-in agent on multiple MDM-designated servers; however, it still was not showing the server details 
  • Confirmed that the user is using the certificate (Self-sign) and the name of the certificate is the same as the MDM server 
 Followed the documentation, Setting up MDM for Windows, and seeing the below errors in the logs.

MainController failure.

Cause

Known issue, where existing functionality does not handle certain situations that may exist in some environments.

Resolution

This was fixed in 8.7.1 as documented in the ITMS 8.7.1 Release Notes under Fixed Issues:
