vCenter Server SSH received disconnect Too many authentication failures

While connecting to vCenter Server Appliance with ssh command I was facing error Too many authentication failures disconnect. I checked ssh settings on the VCSA photon os from VM console but didnt find any issue.

$ ssh [email protected]

VMware vCenter Server 7.0.3.00300

Type: vCenter Server with an embedded Platform Services Controller

Received disconnect from 10.10.10.10 port 22:2: Too many authentication failures
Disconnected from 10.10.10.10 port 22

Finally to resolve this issue I created a file config under C:\Users\Profile\.ssh folder and added below entries for my vCenter Server. Specifically the IdentitiesOnly to yes. You can find the below url about ssh_config for more details.

# Read more about SSH config files: https://linux.die.net/man/5/ssh_config
Host vCenter_or_IP
  Hostname vCenter_or_IP
  IdentitiesOnly yes

Next when you try to connect through ssh.exe command use additional parameter -o PubkeyAuthentication=no. As you can see login is successful.

ssh -o PubkeyAuthentication=no [email protected]_or_ip

VMware vCenter Server x.x.x.xxxxx

Type: vCenter Server with an embedded Platform Services Controller

[email protected]_or_ip's password:
Connected to service
