NSX Manager Disconnected from vCenter

March 6, 2019 Jordansphere NSX

Problem

We noticed NSX Manager had become disonnected from both the lookup service and vCenter

 

Troubleshooting
 

Check Connectivity

From NSX Manager

# debug connection {IP_of_vCenter}

From the NSX Manager logs:

# show logs

I found this snippet – which showed the nsx-user had User account expired

2019-03-06 10:25:31.302 GMT ERROR http-nio-127.0.0.1-7441-exec-5 SoapBindingImpl:133 - SOAP fault
javax.xml.ws.soap.SOAPFaultException: Password of the user logging on is expired. :: Password of the user logging on is expired. :: User account expired: {Name: nsx-user, Domain: vsphere.local}

 

Resolution

Reset the password for the nsx-user in vCenter. Both lookup service and vcenter connections were instantly restored.
