Hi @abanasik,

 

Please go to the machine which has gateway installed, please use ping command in Command Prompt to ping SQL server machine or IP address. Also check if the port used by SQL server service is blocked. For more information, please click on Timeout Expired in this site: https://support.microsoft.com/en-us/help/4009936/solving-connectivity-errors-to-sql-server
