SQL State: HYT00, SQL Error Code 0, Login timeout expired SQL State 08001, SQL Error Code: -1

Gaurav Lohiya 0

I am getting the error "SQL State: HYT00, SQL Error Code 0, Login timeout expired SQL State 08001, SQL Error Code: -1", when trying to link RAD Studio 11.3 with SQL Server.

Along with the above error following message is displayed "A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance.".

Thanks in advance for providing the solution.

That error means what it says: you were not able to reach the SQL Server instance you were trying to connect to. There can be many reasons for this:

Fat-fingering server and/or instance name.
SQL Server not running.
Firewalls blocking.
In case of a name instance, the Browser service not running, or blocked by firewall.
