Description

  • Generic SQL Server Availability - 1433 failed service is in a failed state

Environment

  • N-able N-central 11 or later

Solution

This issue can happen if the Probe or N-able N-central server can't communicate to the SQL server via Port 1433
  1. Ensure that any firewall/gateway device is allowing the traffic.
  2. Check for any AV/software firewall which could be blocking the traffic.
  3. Check manually on the device: Perform a telnet from the Probe to the SQL server using Port 1433

Example:

c:\> telnet <sql server IP> <port>

c:\> telnet 192.168.10.20 1433
