I have created a service fabric stateless reliable service, in which i used OWIN to host a web API. When I deployed the application to the Local cluster, it worked fine and i could call the API.

When i deployed the application to the public cluster, The deployment completed successfully but when i inspected the cluster using Service fabric explorer,

the the replicas seemed to be in "In Build" status for sometime, then it moved to "Warning" State and finally the entire tree in the fabric explorer went red and there are no more replicas present under the partition. And showed the health status as Error. Showing the error "Partition is below target replica or instance count".

Also I used the allowed port for creating the OWIN web server.

This doesn't happen when i deploy the application in local cluster. Service Fabric Explorer Screenshot for public cluster , Service Fabric Explorer Screenshot for Local Cluster

Most of the time this error really just means "we couldn't get your service started." If an unhandled exception in your service is preventing it from starting, you can drill down to your service instance or replica in the Service Fabric Explorer to see a stack trace when it fails to start after multiple attempts.

BTW, I would recommend using the newer web-based Service Fabric Explorer. Just point a web browser to port 19080 on your cluster: e.g., http://mycluster.eastus.cloudapp.azure.com:19080/Explorer/index.htm.
