Review How to connect applications to Azure Database for MySQL. Verify your connection string and other connection settings.On all firewalls between the client and the internet, make sure that port 3306 is open for outbound connections.If this resolves your connectivity issue, remove this rule and create a firewall rule for an appropriately limited IP address or address range. This will open the server to all IP addresses. For temporary testing purposes only, set up a firewall rule using 0.0.0.0 as the starting IP address and using 255.255.255.255 as the ending IP address. Set up firewall rules to allow the client IP address.Steps to resolve persistent connectivity issues User error: You might have mistyped connection parameters, such as the server name in the connection string or a missing suffix in the user name.IP addresses and ports of the server that you cannot to must be allowed as well as application names such as MySQL in some firewalls. Client firewall configuration: The firewall on your client must allow connections to your database server.Server firewall configuration: Make sure that the Azure Database for MySQL server firewall is configured to allow connections from your client, including proxy servers and gateways.If the application persistently fails to connect to Azure Database for MySQL, it usually indicates an issue with one of the following: 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.See Limitations in Azure Database for MySQL. As a server approaches its resource limits, errors can seem to be transient connectivity issue.Review Handling of transient connectivity errors for Azure Database for MySQL for best practices and design guidelines for handling transient errors. Applications that connect to a cloud service such as Azure Database for MySQL should expect transient errors and implement retry logic to handle these errors instead of surfacing these as application errors to users.Check the Microsoft Azure Service Dashboard for any known outages that occurred during the time in which the errors were reported by the application.Steps to resolve transient connectivity issues
Some events can occasionally take longer to mitigate, such as when a large transaction causes a long-running recovery. However, your application loses its connection to the server for a short period of time of typically less than 60 seconds at most. The Azure Database for MySQL service has built-in high availability and is designed to mitigate these types of problems automatically. Transient errors occur when maintenance is performed, the system encounters an error with the hardware or software, or you change the vCores or service tier of your server. Persistent or non-transient errors (errors that regularly recur).Transient errors (short-lived or intermittent).Generally, connection issues to Azure Database for MySQL can be classified as follows: The compute allocation of the server is changed by scaling the number of vCores or moving to a different service tier.Maintenance being performed in the service.Issues with the infrastructure of the service.
