Azure Backup Server: how to fix Error ID 33623?

Question

Hi,

we're trying to install MABS Server and communicate with the VCenter Sphere.

We received this error and the Agent shows the "Error" status.

Do you know how to fix?

We have enabled HTTPS and create a role with administrative privileges.

Thank you,

Andrea

Hello @Andrea Longhitano Thank you for reaching out to us on Microsoft Q&A platform. Sorry for the inconvenience this must have caused you!

Based on the information you provided, I understand that you are trying to install MABS Server and communicate with the VCenter Sphere. However, you are receiving an error 33623.

Azure Backup Server uses TLS 1.1 by default to communicate with the ESXI host.

ESXI host version 6.7 only supports TLS 1.2 protocol.

To configure backup ESXI 6.7 perform the following:

· Enable TLS 1.2 on Azure Backup Server

Note: VMWare 6.7 onwards had enabled TLS as communication protocol.

· Set the registry keys as follows:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v2.0.50727] "SystemDefaultTlsVersions"=dword:00000001 "SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001 "SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v2.0.50727] "SystemDefaultTlsVersions"=dword:00000001 "SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001 "SchUseStrongCrypto"=dword:00000001

Also remove and add again the VMware account on the Azure Backup Server

*Communication should work between Azure Backup Server and ESXI

*Install the agents in the VMs

FYI: These steps should work for your set up and help resolve the issue. Feel free to write back to us if you need further assistance.
