Symptoms

Backup of ESXi configuration of ESXi 6.7 Update 3 (Build 17167734) fails with the following error:

Failed to connect to ESXi host by using SSH

Cause

Issue in the product. The issue is specific to ESXi version 6.7.0 Update 3 (Build 17167734).

Acronis software requires the SSH connection to create the ESXi host configuration backup. Acronis supports the following key exchange algorithms:

diffie-hellman-group14-sha1
diffie-hellman-group1-sha1

Starting from ESXi version 6.7.0 Update 3, the default SSH configuration does not include these algorithms.

Solution

Issue has been resolved in 22.06. Please initiate an update to the latest agent build.
