Those IP addresses match the IP address you have given to the vSphere replication server. I would double check the IP & GW you have set are correct
Yeah, i posted the screenshot of the IP configuration of the Replication Server, confirmed with /opt/vmware/share/vami/vami_config_net and ifconfig too.
I'm managing this web configurator in address https://10.29.250.253:5480
I could see your Gateway is 10.29.0.x whereas the ip address you have set is 10.29.250.x . Is that how your infrastructure is laid out.
As the screenshot shows, it's a /16 network.
The error says that my IP address is not an local address, even if the networks were wrong (it's not) I don't see any relation with this error.
IIRC correctly you'd use 127.0.0.1 for these addresses unless you use multiple virtual network adapters.
Try Adding the vSphere replication server IP address and FQDN on the vSphere replication appliance and add entries for both the appliance and server on the vSphere replication Server /etc/hosts file.
Let me know if it works.
