I am suddenly unable to get connected to the Oracle database from VisualStudio 2022.
The latest build is also not working after the deployment on the deployment server, I cannot see any changes in my checkout files related to the connection string but the previously hosted build is working perfectly at the deployment server.
However, I am still able to connect from SqlDeveloper.
(The only change that I can observe is the windows update)
"DefaultDb": "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=)(PORT=))(CONNECT_DATA=(SERVICE_NAME=)));User Id=;Password=;"
Error: ORA-12545: Network Transport: Unable to resolve connect hostname'

I honestly don't know where to start apart from mentioning I've tried absolutely everything and I feel like banging my head against the wall!
I've configured my IIS according to the Microsoft docs and also added Web Deploy 3.6.
In my services I have the following running:
In my windows firewall I have opened port 8172:
In my IIS I have enabled remote connections:
Within IIS I have a Site which points to an empty folder, when I right click -> Deploy -> Configure Web Deploy publishing I get this:
Using this, I've set up a publish profile in VS like so:
But get this error why I try and 'Validate' the connection:

This error indicates that you cannot connect to the server. Make sure the service URL is correct, firewall and network settings on this computer and on the server computer are configured properly, and the appropriate services have been started on the server.

I can't even remote to this server, I'm accessing it using TeamViewer.
I've viewed EventViewer logs on my local machine and it just says the same error which VS is spitting out.
I honestly don't know what I'm doing and I'd really really appreciate any help
I am remotely debugging my application with azure and VS2019 and it works fine until I have to connect to the database.
Then I get the following error. "The underlying provider failed on Open."
On the other hand, if I debug locally everything works correctly.
Do you have to activate any permission in Azure or in the project config so that the database can be accessed remotely?
Right after the connection string I have put the following.
_context.Database.Connection.Open ();
So it returns the following error to me:
"Unable to connect to any of the specified MySQL hosts".
All this locally does not happen to me. Only when trying to debug remotely.
According to your description, we can ensure that the remote debug function of vs2019 is normal. An error is reported in this _context.Database.Connection.Open (); code. Obviously, the program cannot connect to the mysql database server.
Troubleshooting:
First make sure that your mysql database server can be accessed using tools (such as Mysql Workbench).
Using tools to ensure that the database is accessible is to ensure that the firewall of your database server is open (mysql in azure or other server).
Check the connectionstring of mysql in the released program. According to your error message, it is likely that the connection string is used incorrectly.
I'm trying to setup a startup template to play around with boilerplate and see what it could potentially offer and I'm running into issues setting up my local database.
I've tried the core startup template download as well as MVC 5 and they've both given me the same issue so far. I'll open up the solution in VS 2017, clean the solution, rebuild, enter Package Manager Console and execute Update-Database on the EntityFramework project and I get this error on both projects,
ClientConnectionId:00000000-0000-0000-0000-000000000000
Error Number:2,State:0,Class:20
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)
I'm having a hard time understanding what this might be indicating. I'm pretty sure I've been able to use my local db in other projects recently.
You need to set up an empty database and provide a valid connection string in appsettings.json.
You can use Microsoft's SQL Server.
HI i am getting problem to connect report service thought SSMS instance.
ERROR:
Unable to connect to the server at . The specified URL
might not be valid or there might be a problem with the report server
version or configuration. Specify a different URL, or contact your
server administrator to verify that the report server runs SQL Server
2008 or later. Additionally, if you are trying to connect to a
SharePoint-integrated report server, verify that SharePoint is
installed on the server and that the report server uses SharePoint
integrated mode. (Microsoft.SqlServer.Management.UI.RSClient)
i am using sql server 2012 i dont know why this error comes related to sql server 2008.
could any one help me.
Thanks,

I am using webdeploy to deploy my web application to IIS. I followed Microsoft's 12 part tutorial for this. I successfully deployed it on my local IIS.
I have to now deploy this to production and I am following the same steps. I am connected to the remote machine via VP. Form VS2010 publish profile the connection to the server was successful. But when I enter the DB connection string as
"Data Source=xxxx\SQLExpress;Initial Catalog=SWSS;Integrated Security=True"
and try to preview the Database, I get the following error:
Web deployment task failed. ((4/1/2013 9:18:42 PM) An error occurred when the request was processed on the remote computer.)
(4/1/2013 9:18:42 PM) An error occurred when the request was processed on the remote computer.
Exception has been thrown by the target of an invocation.
Member 'ClassName' was not found.
The remote machine does not have TCP/IP enabled.
1. Is it safe to enable this in production machine?
2. If not, how to deploy DB, taking advantage of the dbdacfx?
Update 1:
Based on the comments below, I have changed my connection string as follows:
"Data Source=SWSS\SQLExpress;Initial Catalog=SWSS;User Id=xxxx;Password=xxxx;"
I created a sysadmin user in SQL server with SQL authentication rather than Windows authentication. Now the error is as follows:
Web deployment task failed. (Could not generate deployment script.
Unable to connect to target server.

Update 2:
Using mixed mode authentication on SQL Server fixed my issue.
