 This indicates that some data cannot be processed in the sync. To find out what is causing the errors, navigate to the CDI page in Braze. Open the **Sync Log** tab to check the error details for the sync job.
 
+### Fixes to common errors seen in test connection and Support emails**
+{% tabs %}
+{% tab Snowflake %}
+- **Error connecting to Snowflake instance: Incoming request with IP is not allowed to access Snowflake**
+  - Update Whitelisted IPs addresses to include Braze IPs. See [Data Warehouse Integrations]({{site.baseurl}}/user_guide/data_and_analytics/cloud_ingestion/integrations/)
+- **Error executing SQL due to customer config: 002003 (42S02): SQL compilation error: does not exist or not authorized.**
+  - If the table does not exist, create the table. If the table does exist, verify that the user and role have permissions to read from the table
+- **Could not use schema**
+  - Grant access to Schema for the user or the role
+- **Could not use role**
+  - Grant user the ability to use the role
+- **User access disabled**
+  - Allow the user access to your snowflake account 
+- **Error connecting to Snowflake instance with current and old key**
+  - Make sure the user is using the current public key as seen in your braze dashboard
+{% endtab %}
+{% tab Redshift %}
+- **Permission denied for relation {table_name}**
+  - Grant usage permission on schema for the user 
+  - Grant select permission on the table for the user
+- **Create Connection Error**
+  - Verify the Redshift endpoint and port are correct
+- **Create SSH Tunnel Error**
+  - Verify public key on your braze dashboard is on ec2 host used for SSH tunneling
+  - Verify username is correct 
+  - Verify the SSH Tunnel is correct
+{% endtab %}
+{% tab BigQuery %}
+- **User does not have permission to query table**
+  - Add User permissions to query the table
+- **Your usage exceeded the custom quota**
+  - Quota needs to be updated to continue syncing at your current rate
+- **Table was not found in location {region} Location**
+  - Verify table is in the specified project and dataset
+- **Invalid JWT Signature**
+  - Make sure that the BigQuery API service is enabled on your account

+  - [Follow instructions in the Databricks knowledge base](https://kb.databricks.com/security/forbidden-access-to-s3-data)
+{% endtab %}
+{% endtabs %}
+
+- **Test Connection runs slow**
+  - Test Connection is running on your data warehouse. Increasing warehouse capcity could help speed it up.  For Databricks, there may be two to five minutes of warm-up time when Braze connects to Classic and Pro SQL instances, which will lead to delays during connection setup and testing, as well as at the beginning of scheduled syncs. Using a serverless SQL instance will minimize warmup time and improve query throughput, but may result in slightly higher integration costs.
