Power BI unable to connect to SQL server - sql-server

It was working at first but then I had this error when trying to connect to an SQL server via DirectQuery.
Edit:
According to this link, I should "run as administrator". Tried that and encountered this error:

In my case, make sure information in Default or Custom, Windows and Database sections are correct and run as administrator. This worked for me

How do I connect to SQL Server from Windows without using trusted_connection?

Struggling with this problem. Right now I am building a service app on a windows machine, which I have been using the following line of code to connect to SQL Server
dbConnect(odbc::odbc(), .connection_string = paste0('driver={SQL Server};server=', SERVER, ';trusted_connection=true'))
It works great, but my issue is that this application I am building will be used on iOS and eventually a Linux container, so I cannot rely on "trusted_connection" going forward. But, the following code fails for me:
dbConnect(odbc::odbc(), .connection_string = paste0('driver={SQL Server};server=', SERVER, ';UID=',USER,";PWD=",PWORD))
In that line I removed "trusted_connection" and put in my user name and password that I use to log into my windows machine, but I get this error:
Error: nanodbc/nanodbc.cpp:950: 28000: [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'fhcrc\sgreenle'.
The user is what I see when I connect to the server through SQL Server Management Studio, and the passwords match, but somehow I still have this error.
Any advice on how to debug or figure this out would be amazing. This has been a thorn in my side for a while and I cannot solve it for the life of me, and I fear that my project will be dead in the water without a solution.
When providing username and password in the connection string, you are using SQL Authentication. Your code sample shows that you are trying to use your Active Directory account for SQL Authentication, but this will not work. You need to create a separate SQL Server account using SQL Authentication and enter those credentials instead.

SQL Server 2008 R2 can't connect to local database in Management Studio

I am using SQL Server 2008 R2 Express.
I first installed SQL Server 2008 R2 Express Management Studio and then I installed SQL Server 2008 R2 Express. I have the instance SQLEXPRESS running and it is set to automatic.
I am trying to connect to it locally using Windows authentication - server name is set to local and the username is grayed out and set to my profile username.
When I try to connect I get the following error:
Have I installed the wrong SQL Server Management Studio?
If your instance is called SQLEXPRESS, then you need to use .\SQLEXPRESS or (local)\SQLEXPRESS or yourMachineName\SQLEXPRESS as your server name - if you have a named instance, you need to specify that name of the instance in your server name.
Your "SQL Server Browser" service has to be started too.
Browse to Computer Management > Services.
Find find "SQL Server Browser"
set it to Automatic
and also Manually start it (2)
Hope it helps.
Follow these steps to connect with SQL Server 2008 r2 (windows authentication)
Step 1: Goto Control Panel --> Administrator Tools --> Services
select SQL SERVER (MSSQLSERVER) and double click on it
Step 2:
Click on start Service
Step 3:
Now login to SQL server with Windows authentication
and use user name : (local)
Enjoy ...
I also received this error when the service stopped. Here's another path to start your service...
Search for "Services" in you start menu like so and click on it:
Find the service for the instance you need started and select it
(shown below)
Click start (shown below)
Note: As Kenan stated, if your services Startup Type is not set to Automatic, then you probably want to double click on the service and set it to Automatic.
I know, this problem can be faced by so many people and many of them have uninstalled and re-installed the sql server for resolving this issue.
In my observation the problem of not connecting the database service locally is just because of your network connection you are using, in most of the cases these problems will come when you are using wi-fi network.
Solution is, if you are using wi-fi then just right click on status of the network and get the ip details and enter the same ip in sql server name,
it will work.

I have the same error but with different case. Let me quote the solution from here:
Luckly I also have the same set up on my desktop. I have installed
first default instance and then Sql Express. Everything is fine for
me for several days. Then I tried connecting the way you trying, i.e
with MachineName\MsSqlServer to default instance and I got exctaly the
same error.
So the solution is when you trying to connect to default instance you
don't need to provide instance name.(well this is something puzzled
me, why it is failing when we are giving instance name when it is a
default instance? Is it some bug, don't know)
Just try with - PC-NAME and everything will be fine. PC-NAME is the
MSSQLServer instance.
Edit : Well after reading your question again I realized that you are
not aware of the fact that MSSQLSERVER is the default instance of Sql
Server. And for connecting to default instance (MSSQLSERVER) you
don't need to provide the instance name in connection string. The
"MachineName" is itself means "MachineName\MSSQLSERVER".
Lots of the above helped for me, plus the accepted answer, but since I was on an EC2 instance, I had no idea what my instance name was. Finally, I opened SQLServer Configuration Manager and in the Name column, use whatever is there as your connection server, so in my case, .\EC2SQLEXPRESS and worked great!
Okay so there might be various reasons behind Sql Server Management Studio's(SSMS) above behaviour:
1.It seems that if our SSMS hasn't been opened for quite some while, the OS puts it to sleep.The solution is to manually activate our SQL server as shown below:
Go to Computer Management-->Services and Applications-->Services. As you see that the status of this service is currently blank which means that it has stopped.
Double click the SQL Server option and a wizard box will popup as shown below.Set the startup type to "Automatic" and click on the start button which will start our SQL service.
Now check the status of your SQL Server. It will display as "Running".
Also you need to check that other associated services which are also required by our SQL Server to fully function are also up and running such as SQL Server Browser,SQL Server Agent,etc.
2.The second reason could be due to incorrect credentials entered.So enter in the correct credentials.
3.If you happen to forget your credentials then follow the below steps:
First what you could do is sign in using "Windows Authentication" instead of "SQL Server Authentication".This will work only if you are logged in as administrator.
Second case what if you forget your local server name? No issues simply use "." instead of your server name and it should work.
NOTE: This will only work for local server and not for remote server.To connect to a remote server you need to have an I.P. address of your remote server.
I had this problem. My solution is: change same password of other in windowns. Restart Service (check logon in tab Service SQL).

Error connecting to SQL Server using SQL Server Management Studio

I've been trying to connect to SQL Server using SQL Server Management Studio to no avail.
This is what the error says:
Cannot connect to .\HAMED.
ADDITIONAL INFORMATION:
Login failed for user 'HAMED'. (Microsoft SQL Server, Error: 18456)
I have an instance of SQL Server by the name of Hamed which is run in Network Sevice mode. I'm using Windows 7.
I'm guessing you didn't grant yourself SQL admin during the install, but are you sure the DB instance is "HAMED"? That sounds like the machine name. Try connecting to .\sqlexpress
Do you remember the SA password? If so, you can add yourself by logging in with that account. Otherwise, you'll have to jump through some hoops and loops to get yourself added.
If you forgot to add yourself to the SQL admin group, read this article:
http://blogs.ameriteach.com/chris-randall/2009/12/11/sql-server-2008-forgot-to-add-an-administrator-account.html
It looks like you're trying to use "SQL Server Authentication" in the login dialog in SSMS, but the user that you're trying to use is a Windows user/administrator? If so, the fix should be as simple as choosing "Windows Authentication" in the drop-down.
UPDATE: looks like I jumped the gun - this sql server forum thread lists lots of possible issues, including permissions issues, orphan users, etc.
sa... the answer was sa.
I had set the administrative password but didn't know the username to go with it. Very nube, I know, you can hit me with it later.
When I installed SQL it asked me to set administrative password - right now SSMS can login.
Under users I see 1\cory (1 is my machine name - I'm trying a numbering scheme). But if I type that in it fails with the error. SQL says "no, that's an NT login, I can't use those".
Under the users list SQL does in fact show the user as Windows authentication but as I said - for some reason I can't connect using Windows authentication. The connection times out.
I'll just add a direct user name here.
All this is to do the MSVA courses for SQL certification. First exam: get sql SSMS to work.

Can't connect to SQL Server Express anymore

I think I made a mistake and I lost my connection to my SQL Server Express.
In SQL Server Management Studio under security I disabled the login option.
Now when I try to connect to the Server I get the message :
"Cannot connect to
HP16969\SQLEXPRESS". Additional
informations : Login failed for user
'HP16969\Bernard (Microsoft SQL
Server, error : 18456)
Is there a way I can correct my earlier mistake ?
Thanks
I really have tried everything but can't connect anymore to SQLEXPRESS. Just because I change The login status to Disabled there seems to be no way for me to reconnect. That is silly!!
I followed the instructions including -m; in the parameter list without any success.
The last option I would like to use is to reinstall Server EXPRESS .After reading many articles on the net I am scared to run into problems...
You need to connect using a login that has access and grant yourself again access back.
If you don't have any login that has access, then you need to restart the server in administrative mode and use a local administrator account to enable back the account 'HP16969\Bernard'. See Troubleshooting: Connecting to SQL Server When System Administrators Are Locked Out.
