-->You receive error messages when the connection to Azure SQL Database fails. These connection problems can be caused by Azure SQL Database reconfiguration, firewall settings, a connection timeout, incorrect login information or failure to apply best practices and design guidelines during the [application design] (sql-database-develop-overview.md) process. Additionally, if the maximum limit on some Azure SQL Database resources is reached, you can't connect to Azure SQL Database.
Transient fault error messages (40197, 40613 and others)
The Azure infrastructure has the ability to dynamically reconfigure servers when heavy workloads arise in the SQL Database service. This dynamic behavior might cause your client program to lose its connection to SQL Database. This kind of error condition is called a transient fault. Database reconfiguration events occur because of a planned event (for example, a software upgrade) or an unplanned event (for example, a process crash, or load balancing). Most reconfiguration events are generally short-lived and should be completed in less than 60 seconds at most. However, these events can occasionally take longer to finish, such as when a large transaction causes a long-running recovery. The following table lists various transient errors that applications can receive when connecting to SQL Database
List of transient fault error codes
| Error code | Severity | Description |
|---|---|---|
| 4060 | 16 | Cannot open database '%.*ls' requested by the login. The login failed. For more information, see Errors 4000 to 4999 |
| 40197 | 17 | The service has encountered an error processing your request. Please try again. Error code %d. You receive this error when the service is down due to software or hardware upgrades, hardware failures, or any other failover problems. The error code (%d) embedded within the message of error 40197] provides additional information about the kind of failure or failover that occurred. Some examples of the error codes are embedded within the message of error 40197 are 40020, 40143, 40166, and 40540. Reconnecting to your SQL Database server automatically connects you to a healthy copy of your database. Your application must catch error 40197, log the embedded error code (%d) within the message for troubleshooting, and try reconnecting to SQL Database until the resources are available, and your connection is established again. For more information, see Transient errors. |
| 40501 | 20 | The service is currently busy. Retry the request after 10 seconds. Incident ID: %ls. Code: %d. For more information, see: • Database server resource limits • DTU-based limits for single databases • DTU-based limits for elastic pools • vCore-based limits for single databases • vCore-based limits for elastic pools • Managed instance resource limits. |
| 40613 | 17 | Database '%.*ls' on server '%.*ls' is not currently available. Please retry the connection later. If the problem persists, contact customer support, and provide them the session tracing ID of '%.*ls'. This error may occur if there is already an existing dedicated administrator connection (DAC) established to the database. For more information, see Transient errors. |
| 49918 | 16 | Cannot process request. Not enough resources to process request. The service is currently busy. Please retry the request later. For more information, see: • Database server resource limits • DTU-based limits for single databases • DTU-based limits for elastic pools • vCore-based limits for single databases • vCore-based limits for elastic pools • Managed instance resource limits. |
| 49919 | 16 | Cannot process create or update request. Too many create or update operations in progress for subscription '%ld'. The service is busy processing multiple create or update requests for your subscription or server. Requests are currently blocked for resource optimization. Query sys.dm_operation_status for pending operations. Wait until pending create or update requests are complete or delete one of your pending requests and retry your request later. For more information, see: • Database server resource limits • DTU-based limits for single databases • DTU-based limits for elastic pools • vCore-based limits for single databases • vCore-based limits for elastic pools • Managed instance resource limits. |
| 49920 | 16 | Cannot process request. Too many operations in progress for subscription '%ld'. The service is busy processing multiple requests for this subscription. Requests are currently blocked for resource optimization. Query sys.dm_operation_status for operation status. Wait until pending requests are complete or delete one of your pending requests and retry your request later.

| 4221 | 16 | Login to read-secondary failed due to long wait on 'HADR_DATABASE_WAIT_FOR_TRANSITION_TO_VERSIONING'. The replica is not available for login because row versions are missing for transactions that were in-flight when the replica was recycled. The issue can be resolved by rolling back or committing the active transactions on the primary replica. Occurrences of this condition can be minimized by avoiding long write transactions on the primary. |
Steps to resolve transient connectivity issues
- Check the Microsoft Azure Service Dashboard for any known outages that occurred during the time during which the errors were reported by the application.
- Applications that connect to a cloud service such as Azure SQL Database should expect periodic reconfiguration events and implement retry logic to handle these errors instead of surfacing these as application errors to users.
- As a database approaches its resource limits, it can seem to be a transient connectivity issue. See Resource limits.
- If connectivity problems continue, or if the duration for which your application encounters the error exceeds 60 seconds or if you see multiple occurrences of the error in a given day, file an Azure support request by selecting Get Support on the Azure Support site.
Implementing Retry Logic
It is strongly recommended that your client program has retry logic so that it could reestablish a connection after giving the transient fault time to correct itself. We recommend that you delay for 5 seconds before your first retry. Retrying after a delay shorter than 5 seconds risks overwhelming the cloud service. For each subsequent retry the delay should grow exponentially, up to a maximum of 60 seconds.
For code examples of retry logic, see:

Steps to fix common connection issues
Make sure that TCP/IP is enabled as a client protocol on the application server. For more information, see Configure client protocols. On application servers where you don't have SQL Server tools installed, verify that TCP/IP is enabled by running cliconfg.exe (SQL Server Client Network utility).
Check the application’s connection string to make sure it's configured correctly. For example, make sure that the connection string specifies the correct port (1433) and fully qualified server name.See Get SQL Server connection information.
Try increasing the connection timeout value. We recommend using a connection timeout of at least 30 seconds.
Test the connectivity between the application server and the Azure SQL database by using SQL Server management Studio (SSMS), a UDL file, ping, or telnet. For more information, see Troubleshooting SQL Server connectivity issues and Diagnostics for connectivity issues.
Note
As a troubleshooting step, you can also test connectivity on a different client computer.
As a best practice, make sure that the retry logic is in place. For more information about retry logic, see Troubleshoot transient faults and connection errors to SQL Database.
If these steps don't resolve your problem, try to collect more data and then contact support. If your application is a cloud service, enable logging. This step returns a UTC time stamp of the failure. Additionally, SQL Azure returns the tracing ID. Microsoft Customer Support Services can use this information.
