I have api appservice in my azure and also I have VM with SQL Server installed.
Now I would like to connect to the database on the vm. I keep getting the following connection error when provide the connection string to api as :
Server=db-svr;Initial Catalog=DBName;Persist Security Info=False;User ID=userid;Password=password;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

My VM -> Overview : There is no DNS name configured and no public ipaddress.
That is the reason I used computer name.
Also the VM->Networking has got the following inbound rule.
Can anyone help how to connect my app service to the SQL Server database available in this VM?
Thanks
This is because they have to talk to each other over the internet, so you have to provide a proper dns name for the sql server or use a static Public IP for it.
You can, technically, use vpn in webapp, but that complicates things a bit.

I am trying to retrieve data from a table located in a postgresql database hosted on azure VM. I would like to inject this data into an Azure SQL Database. I set up the self hosted integration runtime. Since the Vm hosting my DB is a linux VM, i have setup self-hosted IR on windows VM and using that I am able to connect to DB and copy the data to ABS location without any problem but when I try to copy the same data to SQL database, I am getting following error:
ErrorCode=SqlFailedToConnect,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Database: 'XXX', Database: 'XXX', User: 'XXX'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Data.SqlClient.SqlException,Message=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.),

After searching about I opened the inbound and outbound traffic for port 1433 on machine which is hosting IR and and outbound traffic for port 1433 on machine which is hosting the database but I am still getting the same error.
Any idea what am I missing here?
I managed to solve the problem. As per azure documentation here, if we are trying to connect to SQL database from within Azure cloud then we need to open communication to port range 11000-11999. We need to put this port range in network security list for outbound connections.
I have my data migrated to managed instance and configured fail over group. But not able to connect to my database using SSMS .I have also tried connecting by giving database name in options

Failover group listener endpoint is basically a DNS record pointing to the private IP address of the current primary of failover group. The error message indicates that there is no network path between the client machine running SSMS and managed instance injected into your VNet within your private IP address space.
Given this error message I would expect that you cannot connect from the same client machine even using fully-qualified name of the instance itself.
Do you have P2S, S2S or Express Route established between the two locations?
Is it possible to connect an Azure Web App to a SQL Managed Instance via the private endpoint for the MI?
Following the documentation here https://learn.microsoft.com/en-us/azure/sql-database/sql-database-managed-instance-connect-app it seems to be that as long as the web app service is in the same VNET as the managed instance, then the connection should be OK via the private endpoint.
I have enabled VNET integration on the app service so that it is integrated into the same VNET as the managed instance. I have also whitelisted all of the outbound IP addresses for the webapp (including the additional ones) on port 1433 for the MI.
Using the private connection string for the MI, the webapp fails to connect when loading the front end and also when checking the connection string via the diagnostic tools.
Enabling the public endpoint on the MI and whitelisting all outbound IPs on port 3342, the webapp is able to connect straight away with no issues. Switching back to the private endpoint fails again.
The error message received is:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Came across this issue as well, a simple restart after the vnet-integration activated the connection for me
I am trying to connect to a SQL server running on an Azure VM using the below sample code (having defined the SQL user name and password):
$SqlCredential = Get-AutomationPSCredential -Name $SqlCredentialAsset
# Get the username and password from the SQL Credential
$SqlUsername = $SqlCredential.UserName
$SqlPass = $SqlCredential.GetNetworkCredential().Password
# Define the connection to the SQL Database
$Conn = New-Object System.Data.SqlClient.SqlConnection("Server=tcp:$SqlServer,$SqlServerPort;Database=$Database;User ID=$SqlUsername;Password=$SqlPass;Trusted_Connection=False;Encrypt=True;")
this code works when I am connecting to Azure SQL Database , but not when connecting to SQL running off Azure VM.
the error thrown is:
Error occured: Exception calling "Open" with "0" argument(s):
"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 - No such host is known.)"
I have verified on the VM SQL remote connections are enabled and including TCP port 1433 defined.
Probably it's a network related issue. If you have verified on the VM SQL remote connections are enabled and including TCP port 1433 defined. Also, the port 1433 was opened in the inbound port rule of NSG attached to the VM and windows firewall inside the VM. You could use telnet verify this port locally.
Moreover, you could specific $SqlServer= "sqlvmlabel.eastus.cloudapp.azure.com"which is a public DNS name of Azure VM. Here is an example of a connection string for using SQL Authentication.
Server=sqlvmlabel.eastus.cloudapp.azure.com;Integrated Security=false;User ID=<login_name>;Password=<your_password>

I'm trying to connect Azure's SQL database via SQL Server 2008 R2 SP2. I'm using Azure with free trial subscription. I already search everywhere and tried these things:
Allow inbounds and outbounds rule in windows firewall for port 1433
Check that TCP connections in SQL Server Configuration Manager is available and running on port 1433
Create server and database on azure portal and configure its ip allowance
I connect with these settings
Server Type: Database Engine
Server Name: tcp:aaa.database.windows.net,1433 / aaa.database.windows.net
Login: bbb#aaa
Password: xxx
And the error is
"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) (Microsoft SQL Server, Error: 10060)"
P.S. I also can't ping xxx.database.windows.net and can't telnet xxx.database.windows.net 1433
Your question is confusing, as you're talking about both SQL Server and SQL Database. But, given the connection strings you mentioned (xxx.database.windows.net) you are definitely talking about SQL Database service, not SQL Server in a VM.
That said: You must allow certain IP addresses to connect to it (this is a built-in part of the service itself). Look at the SQL Database server's Firewall setting:
You'll need to add the IP address of your computer (or IP range), to access SQL Database through your local tools.
