I created a new Azure SQL Managed Instance and obtained the connection string from the Azure Portal. However, I am unable to connect to the server from SQL Server Management Studio. The connection hangs and times out with a network error.
You need to configure the public endpoint and ensure you're using the public connection string, including port 3342 at the end of it.

I have a setup where the connection string of my .NET application is configured at the app service level and the database used in it is present in an Azure SQL VM
I see the following error, while accessing my Web APIs in the app service
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 - Access is denied.
However, I’m able to connect to the database directly on my local system using SSMS with my organisation’s VPN
I’m struggling to find the right resource, appreciate if you someone can help me with steps to fix it
i just have the beginner level knowledge on Azure platform
I tried to reproduce the same in my environment I got the same error like below.
To resolve this issue i have removed private access and tried and then added new private access its work successfully.
Check the public access in selected network with firewall rule and allow exception as below.
And, when I remove this private endpoint and try to add new private access i can able to connect with my sql server.
Check this connectivity as below.
My azuresql,database server connected successfully.
Note: This error may occur in multiple ways if are not enable sql services and in tcp/Ip If any of the protocols are disabled or if Remote Connection Permission is disable error may occur for this please refer the below documents.

I Created a Web App,
Ive setup a Azure sql server with a private endpoint
Created a Azure SQL database on the above sql server
Created an endpoint for SQL server database and added firewall rule
to allow azure services through, also added vnet where private
endpoint is on to the firewall
However when i try to tcpping to the azure sql database from the console of the web app, i keep getting connection failed?
Any ideas?
ok it seems you need to append :1433 at the end of the tcpping otherwise it wont work! Go to your web app console and type the below in substitute the "adbsql01" with your sqlservername
eg
tcpping adbsql01.database.windows.net:1433
Due to what is happening right now in the world, azure seems to have run out of space. Currently, you cannot create a new SQL Server therefor no SQL Databases. Does anyone have experience or knowledge on how to Connect the Web App hosted on Azure to the GoogleSQL SQL Server? It's the only viable cloud service I found that can be free for some time until azure is back online. I cant figure out how to get the connection strings and how to allow connections etc. There is minimal documentation on SQL Server from googles side.
Thank you in advance,
Mike
For connect to Cloud SQL you need to enable the Public IP of your database and whitelist the Public IP of your Azure app to Allow connections between Azure app and Cloud SQL
The only way to connect to Cloud SQL from the external services is via IP connection in this document is explained step by step how to enable Public IP for your SQL server and how to whitelist the incoming IP addresses.
I found this article about how to create a connection string using public IP
I'm trying to use Azure SQL Managed Instance server (with public endpoint disabled) as datasource for Azure Search Service indexer. When I try to create indexer in Azure Search, getting 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. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
Below is the connectionstring I used for Azure Search datasource.
Server=tcp:mymanagedinstance.database.windows.net,1433;Database=dbname;User Id=username;Password=password
I have added below inbound rules in SQL managed instance subnet's NSG. But still I'm unable to connect to managed instance from Azure Search.
Can someone advise is there any other configuration I should do.
I believe you do have to have the public endpoint enabled to index your SQL data via Azure Search. You should be able to enable the public endpoint to only allow "Azure Services" though. See below documentation for screenshots/more context.
"As noted in Connecting Azure SQL Database to Azure Cognitive Search using indexers, creating indexers against SQL Managed Instances is supported by Azure Cognitive Search through the public endpoint."

I've built a Windows container with my app inside and ran it locally. The app in the container connects to an Azure SQL Database, using the domain name from the connection string. SQL Server is configured to accept clients from any IP and from Azure Services.
Everything works fine locally. But when I run my container in Azure Container Instances, I get the following standard 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: TCP Provider, error: 0 - A connection attempt failed
because the connected party did not properly respond after a period of time,
or established connection failed because connected host has failed to
respond.)
You need to create a managed identity https://learn.microsoft.com/en-us/azure/container-instances/container-instances-managed-identity and grant that identity permission to the SQL database.
You can then use the Microsoft.Azure.Services.AppAuthentication library to get an access token and use it during authentication. This is only available in dotnetcore 2.2 and .net 4.6 and above.
string connectionString = "Data Source=<AZURE-SQL-SERVERNAME>; Initial Catalog=<DATABASE>;";
SqlConnection conn = new SqlConnection(connectionString);
conn.AccessToken = (new AzureServiceTokenProvider()).GetAccessTokenAsync("https://database.windows.net/").Result;
conn.Open();
More info can be found in the below links. None of them are explicitly for ACI but it should be basically the same from a code perspective once you have created the MSI.

I've experienced a similar issue with a Windows container in ACI trying to connect to an Azure SQL database. For some reason, DNS was not working inside the container. I could not resolve any public DNS names. Inside the container, DNS was pointed to a 10.x.x.x address. I never set this as part of the image build so I assume ACI is setting this as part of DHCP.
To fix this I ran the following as part of my PowerShell entrypoint script:
$nic = Get-NetAdapter
Set-DnsClientServerAddress -InterfaceIndex $nic.IfIndex -ServerAddresses ('1.1.1.1','8.8.8.8')
