My problem was with the time of SqlAzureExecutionStrategy, was stablished in 300 secods (5 minutes) and the operations I was doing took more than 5 minutes:

Imports System.Data.Entity
Imports System.Data.Entity.SqlServer

Namespace Models
    Public Class ModelConfiguration
        Inherits DbConfiguration

        Sub New()
            ' https://docs.microsoft.com/es-es/ef/ef6/fundamentals/connection-resiliency/retry-logic

            ' WebConfig
            Dim AzureBBDD = ConfigurationManager.AppSettings("AzureBBDD").Equals("SI")

            ' If AzureBBDD == "SI"
            If (AzureBBDD) Then
                ' WebConfig, here was the problem, low value in seconds...
                Dim AzureBBDDMaxTimeSeconds = Integer.Parse(ConfigurationManager.AppSettings("AzureBBDDMaxTimeSeconds"))
                SetExecutionStrategy("System.Data.SqlClient",
                                 Function()
                                     Return New SqlAzureExecutionStrategy(Integer.MaxValue, TimeSpan.FromSeconds(AzureBBDDMaxTimeSeconds))
                                 End Function)

            End If
        End Sub
    End Class
End Namespace
