Hi,

Most likely you got this error because you changed sandbox network configuration and don't regenerate new SDK. Note that operations service embeds list of ip addresses/hosts of bootstrap servers in SDK.

Refer to this and this thread for more details.

Best regards,
Peter.

[Manoj Verma]

No i didn't that's fresh kaa ova installation.

I did the same with regenrated SDK but still the same error. :(

[Peter Krutsiuk]

Hi,

1) What kind of network did you choose in VirtualBox network configuration section for Sandbox VM - Bridge mode or NA?

2) If VM configured to NAT check out content of /etc/hosts file, localhost must be set to 127.0.0.1.

Also some useful information you can find in threads that I mentioned before.

Best regards,
Peter.

[Manoj Verma]

Hi Peter

Thanks for your continous support.

1) What kind of network did you choose in VirtualBox network configuration section for Sandbox VM - Bridge mode or NA?

bridge

2) # Interface that will be reported by all transports

transport_public_interface=192.168.0.103

I regenrated SDK and build with max trace i am getting gollowing trace

Hi,

Can you ping Sandbox from machine where you running the sample app?

Best regards,

Peter.
