Cause

Environmental - Network
The "TCP" error indicates that there is a network connection issue between Tableau Desktop or Tableau Server and the Azure Synapse Analytics server.
Ratkaisu
Work with your IT network team to configure the network setting to access Azure Synapse Analytics server.
Check that your firewall allows outgoing TCP communication on TCP port 1433, since the SQL Azure Database / Azure Synapse Analytics service is only available with TCP port 1433. 
For more troubleshooting information, please refer to the Microsoft document Azure SQL Database and Azure Synapse IP firewall rules - Troubleshoot the database firewall .
