I'm installing an application and getting following error:
Can't connect to SQL Server DB.
Error: The TCP/IP connection to the host , port 1433 has failed.
Error: : Connection timed out. Verify the connection properties.
Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connection at the port.
Make sure that TCP connections to the port are not blocked by a firewall.
Can someone please advise me?
Issue resolved with the help of SQL Server configuration Manager

Hope I'm doing this right as this is my first StackOverflow question. I'm trying to SSH into a server, but running the ssh command results in a connection timeout (using the MobaXTerm client on Win10). I'm trying to connect on port 22, and have gone through Windows Firewall to make rules to open the port, but it's still not working. Any ideas as to why this is happening? I can provide relevant information as needed.
Thanks in advance!
That error message means the server to which you are connecting does not reply to ssh connection on port 22. I think three possible reasons for that:
The server has not installed ssh
You are running ssh with different port
The machine has a firewall that doesnot allow you to connect
I'm having a hell of a hard time trying to figure out why I can connect to my SQL Server using Management Studio using my local ip or local computer name or sql instance name but I can't connect to the same SQL Server using my public ip address.
I have tried all of the below steps but nothing seems to fix the Wait Operation Timed Out error message:
Disabled firewall on the SQL Server and the computer I'm trying to use to connect with.
Port forwarding is enabled for the port I'm using which is the default 1433
Ran the telnet command: telnet publicip port from a computer outside of my network and it was successful
Restarted the SQL Server plenty of times
Enabled remote connections for the server and enabled tcp/ip for the 1433 port
I also enabled port forwarding for the sql browser service using the recommended port of 1434 via udp
Tried to connect with named instance but only works with local ip and not public ip
I am pretty much out of ideas at this point so any help is greatly appreciated
Here is the full error message just in case anyone needs to see it:
Cannot connect to XX.XX.XXX.XXX,1433.
ADDITIONAL INFORMATION:
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. (provider: TCP Provider, error: 0 - The wait operation timed out.)

I want to create localhost connection in Oracle SQL Developer tool
my credentials are
username : SYSTEM
password : SYSTEM
Hostname :localhost or 127.0.0.1
port : 1521
sid : xe
When i connect i gives error The Network Adapter could not establish connection
The Network Adapter could not establish connection is caused because:
The database host name or port number is wrong.
The listener process (service) is not running. You can re-start it with the "lsnrctl start" command or on Windows by starting the listener service.
you have either the wrong SQL Developer URL or you have a basic SQL*Net connectivity issue! This error is most likely caused by one of these factors:
You are using the wrong URL
The wrong port number or IP address (or DNS host name) was used
The listener is not configured properly
The listener process (service) is not running. You can re-start it with the "lsnrctl start" command or on Windows by starting the listener service.

I'm having a heck of a time getting a MS SQL datasource connected through my railo installation. I can connect fine through Adobe ColdFusion, but railo keeps throwing an error
In Adobe ColdFusion I have my server set as mycomputername\sqlexpress and port 1433. In Railo using the same server, database, username and password. I'm getting the following error
The TCP/IP connection to the host myservername, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port."..
I've also tried connecting via the IP address listed in SQL Server Configuration Manager IP4 is set to active and enabled with an IP address of 127.0.0.1 but that throws the same error as above
I have IPv6 turned on and that shows up as IP1 in my TCP/IP settings, but I don't know why that would be causing an issue.
Port 1433 is open as I can connect through Adobe ColdFusion. I hope I'm missing something obvious, but I'm stumped.
I finally got this working by changing the Listen All setting to no in SQL Server Configuration Manager > TCP/IP Propertiest
and setting the TCP Port to 1433 and enabling the datasource in IP2 below
I was able to connect to MSSQL 2008 express on local machine using SQL server management Studio for host 'nash-pc\sqlexpress'. But when I connect with Microsoft JDBC driver it gives me error like below. JDBC has problem with having '\' in the host name? I'm not sure how to make host name to become 'localhost' instead of 'nash-pc\sqlexpress'. funny thing is that if i use server name as 'localhost' then I could not even connect with SQL server management Studio.
"The driver encountered an unknown error: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host nash-pc, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port."."
