Switch port configured for 802.1X authentication does not respond to end client request

We have port security configured in the environment.I have observed that couple of machines fail to go online when port security is enabled. After working with MS to diagnose everything on the OS side it was determined that the end client is sending domain credentials for 802.1X authentication, but  the authenticator is not responding to the request.

 

Here is a snippet of network trace

 

 

Output omitted.... 

 

Microsoft_Windows_OneX

Port(2): Sent an Eapol start packet        

1495        

4.9998892

 

 

Microsoft_Windows_OneX

Port(2): Completed the 802.1X authentication because no authenticator was found

 

Another network engineer has been succesful in the past just changing the port and all is good. I am wondering if anyone has come across such issue.

 

Thanks,
