Failure to winrm authenticate against Windows7 after months of working?

I have a Windows7 computer that last month I took offline and replaced with Windows10 system with a different name.

I as using Ansible + winrm with no problems on this Windows7 system.

Power this Windows7 system up and now Ansible is complaining that I cannot authenticate.

`
<10.xxx.xxx.xxx> ESTABLISH WINRM CONNECTION FOR USER: Administrator@XXXX.YYYYY.COM on PORT 5986 TO 10.xxx.xxx.xxx
fatal: [reporter.xxxx.yyyyy.com]: UNREACHABLE! => {
“changed”: false,
“msg”: “kerberos: authGSSClientStep() failed: ((’ Miscellaneous failure (see text)', 851968), (‘Server (krbtgt/xxx.xxx.xxx XXXX.YYYYY.COM) unknown’, -1765328377)), ssl: auth method ssl requires a password”,
“unreachable”: true

`

}

It’s still part of the realm, I can still RDP and authenticate as Administrator@XXXX.YYYYY.COM the only thing I see odd is

<10.xxx.xxx.xxx> ESTABLISH WINRM CONNECTION FOR USER: Administrator@XXXX.YYYYY.COM on PORT 5986 TO 10.xxx.xxx.xxx

Normally I would see something like

<PC-HOSTNAME.XXXX.YYYYY.COM> ESTABLISH WINRM CONNECTION FOR USER: Administrator@XXXX.YYYYY.COM on PORT 5986 TO 10.xxx.xxx.xxx

Forward and reverse DNS are correct.

How can I debug this further?
