             Summary: .NET: communication problems between Apache Ignite server in Azure Kubernetes and thin clients in Azure Web Apps
                 Key: IGNITE-14695
                 URL: https://issues.apache.org/jira/browse/IGNITE-14695
             Project: Ignite
          Issue Type: Bug
          Components: platforms
    Affects Versions: 2.10
         Environment: Apache Ignite: v2.10.0

JDK: v1.8

.NET Core: v3.1
            Reporter: Danut Radoaica


If the Apache Ignite server and thin clients are in Azure Kubernetes there are no problems.

If the Apache Ignite server is in Azure Kubernetes and the thin clients are in Azure Web Apps (same subscription) we always receive this error:
