Target IP is added to TrustedHosts. Still getting WinRM authentication failure???

[Sanya2]

We are getting the following WinRM error despite adding this IP address in the TrustedHosts. What could be the reason?
WMI query on host 10.x.x.y authentication failure. query: Select * From Win32_Process WHERE (ProcessId = 324708) error: Winrs error:The WinRM client cannot process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config.. Access is Denied

Here's the detail from ecc logs;

Hello Sanya,

check once if the credential are correct. Or you can run quick discovery for this particular IP address you can get to know IP address is reachable or not.

Please let me know if it works.

Kindly mark an answer as correct and helpful if it will resolve your query.

Regards,

Akshata

Credentials are working fine. Above message & log type is when I did the quick discovery.
