Error while onboarding new windows local connector

[shekhardas1825 (Shekhar Das)]

Hi Experts,

We are getting an error Exception occurred while executing the RPCRequest: Errors returned from IQService. Unspecified error while onboarding a new windows local connector and running a test connection.

IQService is up and running, FYI - Active Directory and other configured windows local sources are also working as usual.

We have followed every steps from below troubleshooting document, but still getting the same error:
Troubleshooting

We have restarted IQServices as well.

We can see below error in IQTrace logs:
