Did not find workers on iometer when install vmware-io-analyzer-1.6.2

I deployed "vmware-io-analyzer-1.6.2.ova" on two  ESXi hosts say as ESX1 and ESX2. followed all instructions mentioned in user guide

1. io-analyzer1 on ESX1 and io-analyzer2 on ESX2.
2. Launched Io analyzer GUI
3. Created Workload Configuration
4. and started Run

I did not see any workers added on iometer.

I am not understanding how it is working.

Please find attachments for logs.

It will be good if i get some help on it.

Thanks
