MBE-426 Cluster with IPv6 leads to agent crash when stealing

@sahityacodes does your pod have both ipv6/ipv4 or only ipv6? because if only ipv6 this will be harder to fix.

[sahityacodes]

Our pod is deployed with istio proxy container. The main application itself contains IPV4 only, however when deployed in a cluster that supports dual stack configurations, istio proxy can work with both IPv4 and IPv6 I suppose. So, I guess it has both IPv4 and IPv6

Ok so I believe my fix would work for your case :)
