Issue/Introduction

  • You are unable to access the Local manager from the global manager UI.
  • Login works correctly on the local manager directly.
  • When you try to review the DFW (Distributed Firewall) hit count, you see the following error:
On local manager: "Error: No server's available: Error code 98"
On Global manager: "Error: No server's available: Error code 100"
  • On the Local Manager (LM) logs, we see the following error:

Environment

VMware NSX-T Data Center 3.x

You are using Federation and recently changed certificates on the NSX-T Managers.

Cause

This issue occurs due to how the federation Global manager imports new certificates for the local manager and does not update the old thumbprint in place on the Global manager, which causes communications issues between the Global managers and the Local managers.

Resolution

Workaround:
Update the Thumbprint on the Global Manager:

  1. Browser to the LM site, find the SHA-256 Thumbprint.
    • In Chrome, other browsers may be different, this can be down by clicking the lock symbol in the address bar.
    • Selecting Connection is Secure and then clicking Certificate is Valid, you will be present with the certificate Thumbprints of the LM.
  2. It should look like:

    56 32 91 96 66 68 B9 C7 9F 05 40 A0 DA 0C E4 ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## 


  3. Replace all spaces with nothing, so it becomes:

    563291966668B9C79F0540A0DA0CE4##################################

  4. Login to the GM and go to 'System->Location Manager'.
  5. Select 'Actions->Edit Settings' for relevant LM site, where we just got the Thumbprint for.
  6. Add the Thumbprint, without spaces, to SHA-256 Thumbprint field and the required password.
  7. Then click 'Check Version Compatibility' button in same box.
  8. Then click the 'Save' button.
