The Orleans/ShoppingCart setup fails when try to deploy on Web App on Both Production and Staging slot

**Issue descriptions**
Using the project Orleans/ShoppingCart, I was able to build and deploy successfully on Azure Web App. Also, to build a new Environment on Azure I used the bicep templates mentioned [here](https://github.com/Azure-Samples/Orleans-Cluster-on-Azure-App-Service/tree/main/.github/workflows/flex). Everything worked fine till this point.
Then I created a Staging Slot copying the production slot configuration and deployed the same ShoppingCart build. The Staging Slot Silo is stuck in the Joining state giving the below error.

```
Exception while sending message: Orleans.Runtime.Messaging.ConnectionFailedException: Unable to connect to endpoint S172.17.0.254:20106:31922292. See InnerException

```

If I open Kudu on Staging Slot, and try to ping the Production Silo address, I get the following exception:

```
PS C:\home> tcpping 172.17.0.254:20106
tcpping 172.17.0.254:20106
Connection attempt failed: An attempt was made to access a socket in a way forbidden by its access permissions 172.17.0.254:20106
```

Anyone got any ideas as to what could be wrong?
