I think probably you haven't configure any Azure DB firewall rules to allow your computer's IP to communicate with your Azure DBs.
Simple things to check (not sure what you've tried so humour me here):
You're connected to the outside network.
Instance\Database name, username and password are correct.
Instance and database are online and connectable (Azure servers not down for scheduled maintenance or run out of paid services.)
Firewall rules are incorrect.
Also I think this question here is identical to your question. Try checking that out.

I cannot connect to any remote SQL Server instances from my system. I used to connect them from SQL Server Management Studio. Moreover, I can still connect to the same SQL Servers remotely from another systems (my colleagues' system).
I am getting following 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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Error Number: 53
Severity: 20
State: 0
I have checked:
Named pipes/TCP is enabled.
Remote connections are allowed.
Windows Firewall is off.
Enabled everything in SQL Server Configuration Manager.
Also, I have tried everything mentioned in this post-
How do I fix the error 'Named Pipes Provider, error 40 - Could not open a connection to' SQL Server'?
But still could not solve my problem. Please suggest any method which allows me to fix this error and connect to the remote servers again.
instead of check whether that server system is working or not, because sometimes if the server system is not working means we are unable to connect to that system
I have an AWS RDS SQL Server instance (Express edition). Initially, I created a t2.medium instance. I was able to connect to it from my SQL Server 2012 Management Studio without any problems.
But now I modified my RDS instance from t2.medium to t2.micro (free trial version) by using the Modify Instance option. The modification was done successfully. No other changes were done, but now I am unable to access the instance through the SQL Server 2012 Management Studio. The server name, port, and credentials are all same as before. For testing purposes, the VPC security group has the incoming rule set to allow "All Traffic at all times". But somehow the following error appears whenever I try to connect.
"Cannot connect to ...

(.Net SqlClient Data Provider)"
Kindly help me, as I am unable to easily access my database. If there is any other way to access the database easily do let me know.
Please, apart from management studio, is there any other tool which can be used to connect to a database on a hosting server online. Because I've tried so many times with management studio with the right credentials but I'm still not able to connect. I've disable all firewalls, made the right configuration but I'm still not able to connect.
when I connect I get this error

When I connect to SQL Azure from my code, I get the following error.. I am able to connect to SQL Azure from SQL Server Management Studio successfully.
System.Data.SqlClient.SqlException: 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 requested name is valid, but no data of the requested type was found.)
I also tried connecting using sqlCMD and that connects without any issue. Only issue arises is during runtime when I get this exception.
You might also want to check to make sure your firewall allows outbound connections on port 1433.
There can be numerous reasons for this failure, I am listing out the scenarios and the options that needs to be allowed on the server.
If you are connecting an Azure SQL Instance using Sql server management studio while inside you company's network/firewall, first of all you will need to check if your company's firewall rules allow that or not.
On the AZURE SQL Server, make sure your IP address is in the allowed list.
I believe you just need to tick the checkbox "Allow other Windows Azure services to access this server" in Firewall Rules on your SQL Azure account (this will allow connecting to the db server from your deployed Azure application). Hope this helps.
It would be helpful if you post your connection string here. Also a sample app on connecting to sql azure using ado.net: http://msdn.microsoft.com/en-us/library/windowsazure/ee336243.aspx
Makesure you pay attention to the SqlConnectionStringBuilder properties.
If you have your IP added into firewall rules and allowing SQL
connection to Azure Services Enabled. It should work fine!
I am new to managing servers but I have just been given full access to set up an MS SQL Database on win server 2003. I have created a Database successfully and can connect locally (via remote desktop server)
Problem is I can't connect to the database from my personal computer (remotely, via ms sql server management studio). I have followed several tutorials such as: http://blog.sqlauthority.com/2009/05/21/sql-server-fix-error-provider-named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error/
The error I am receiving is:
Cannot connect to 'servername'
ADDITIONAL INFORMATION:
A network-related or instance-specific
error occurred while establishing a

Verify that the instance name is

Any help will be great, thanks!
"SQL Server is configured to allow remote connections"
You need to enable remote tcp/ip connections in sql surface area configuration. It's new in 2005 and then dropped in 2008.
If that doesn't work, you either have a network issue are are perhaps giving the wrong name - maybe you installed a named instance?
