When working with Azure, you may encounter the following error:
A transport-level error has occurred when receiving results from the server. (provider: TCP provider, error: 0 - An existing connection was forcibly closed by the remote host.)
This error occurs because Azure closes idle connections. Azure uses a connection pool to keep low-level connections open to improve performance when reopening them. However, dbForge Studio for SQL Server uses the ADO.NET model, where the pool timeout is set to 10 minutes, while Azure closes connections after 5 minutes of inactivity. This mismatch leads to the error when trying to access data.
This issue is caused by the connection timeout settings in Azure. To resolve it, Microsoft ADO.NET developers should adjust the timeout behavior. Alternatively, you can work around the issue by increasing the connection timeout in your Azure environment or reducing idle times during data comparison.
