Cannot complete login due to an incorrect user name or password

Hello everyone,

I have an Dell server running ESXI 6.0 latest version on standalone mode. Not connected to any vCenters.

The problem i have is every couple of days I get the message :

Cannot complete login due to an incorrect user name or password


Even my credentials are correct.( username root ) My esxi has static public address and everything else is working fine.

After a couple of tries, still same error, wait a couple of hours and then login again as normal.

What can be the issue?

Is doing this every one day or two.

Thank you in advance.

Are you connecting via hostname or IP?

I wonder if DNS is giving you problems?

Hello,

take a look at the end of this article

https://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.vsphere.security.doc%2FGUID-DC96FFD...

"Starting with vSphere 6.0, account locking is supported for access through SSH and through the vSphere Web Services SDK. The Direct Console Interface (DCUI) and the ESXi Shell do not support account lockout. By default, a maximum of ten failed attempts is allowed before the account is locked. The account is unlocked after two minutes by default."

If your ESXi has a public ip address it might be a brute force attack that got your root account locked for some time.
