On our 6.5 vcsa in /var/log/vmware/vsphere-client/logs/vsphere_client_virgo.log I'm seeing a lot of errors like this:
[2019-03-12T15:47:50.299Z] [ERROR] data-service-pool-777 70006708 100026 200013 com.vmware.ph.impl.PhoneHomeClientImpl java.net.NoRouteToHostException: No route to host (Host unreachable) com.vmware.vim.vmomi.client.exception.ConnectionException: java.net.NoRouteToHostException: No route to host (Host unreachable)
Just wondering how to fix this?
