We lift and shifted our cloud services to Azure Service Fabric. We converted our services to Windows Container and successfully deployed to the cluster. However, we're getting a lot of timeout issue while uploading file to Sharepoint and accessing Azure SQL Server.
See the example below:
SQL: A transport-level error has occurred when receiving results from the server. (provider: Session Provider, error: 19 - Physical connection is not usable)
Sharepoint: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.
Note: These issues are not happening is cloud services.
