I have tried inbound rules for all ports in my firewall but did not work.

In SQL Configuration Manager: everything is enabled and SQL Server, SQL Browser and SQL Agent are running.

I have also tried deleting IPV6 from msmdredir

I don't know whats left or what is happening.

Need some support please.

Moreover, I am using Latest Sql Management studio and SQL Server.

Hi @Bhrigwish -- Are you still experiencing an issue while attempting to connect to the SQL Server instance?  Thanks.

@Bhrigwish Are you connecting using SQL Login or Windows NT?  

Try checking if the SQL Service is running. You can also check from the service the name of your Instance which is usually written inside a parenthesis like SQL Server (SQLEXPRESS) "Ooops you've checked this already"

Have you tried using IP Address? e.g. 192.168.1.1\SQLEXPRESS

Also, try pinging your SQL Server if there's a reply.
