Hi all,
I have configured a 2 node windows failover cluster having 4 instances in it in Azure VMs.
I have also configured an Azure Internal load balancer and provided health probes and front-end IPs for the 4 instances.
SQL Browser service is running and I have configured UDP port 1434 as one of the load balancing rules for each of the frontend IP for 4 instances.
Firewall is off for the 2 nodes and NSG is all allowed.
I have 2 instances running in node 1 and 2 instances running in node 2.
If I connect to node 2 instance from node 1 SSMS, it throws below error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
I can telnet the ports from node 1 and node 2 .
Can anybody help in resolving the issue?
Do I have to do any setting in ILB for the 4 instances?
Regards,
Yasir
