I apologize, but you haven't provided the specific error message you're encountering with the Airbyte SQL Server source connector. Without knowing the exact error, I can't provide a precise answer. However, I can offer some general guidance based on common issues with the SQL Server source connector in Airbyte: 1. TLS/SSL Errors: If you're experiencing TLS-related errors, it's often due to version incompatibility. Airbyte supports TLS 1.2 and 1.3, but not TLS 1.0. You may need to enable a higher TLS version on your SQL Server. [Github Issue](https://github.com/airbytehq/airbyte/issues/30287) 2. Connection Issues: Ensure that your SQL Server is accepting TCP/IP connections and that the port (usually 1433) is not blocked by a firewall. [Forum Post](https://discuss.airbyte.io/t/2892) 3. Named Instance Issues: If you're trying to connect to a named SQL Server instance, make sure you're using the correct format for the host name. [Forum Post](https://discuss.airbyte.io/t/2892) 4. Data Type Incompatibilities: Some data types in SQL Server may not be compatible with Airbyte's replication process, especially when using columnstore indexes. [Forum Post](https://discuss.airbyte.io/t/3646) 5. CDC-related Issues: If you're using Change Data Capture (CDC), be aware of retention period limitations. Airbyte may trigger a full refresh if the CDC logs are no longer available.
