Creating a local connection in Oracle SQL developer 12c - oracle-sqldeveloper

Not sure if I'm missing anything.
I'm trying to create a local connection in order to create a new user in Oracle SQL developer 12c. (AVOIDING CDB connection)
After browsing for an hour, came across 2 methods.
Using connection type as "Local/Bequeath"
Throws following error (Status : Failure -Test failed: ORA-01017: invalid username/password; logon denied)
Using connection type as "Basic", Hostname as "localhost", Port as "1521", and Service name as "XEPDB1"
Throws following error (Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor)
Thanks.

ORA-12170: TNS:Connect timeout occurred IBM Cloud Pak

I was trying to connect DataStage on IBM Cloud Pak to my Oracle database using 'Oracle (optimize) connection' and kept having the error said:
"The test was not successful.
The assets request failed: Connection failed: {"failure_message":"[The connector could not establish connection to the specified Oracle server. Method: OCIServerAttach, Error code: 12170, Error message ORA-12170: TNS:Connect timeout occurred.]","status":"failure"}". What is the possible reason, and what should I do?

.NET 5 Connecting to MS Access mdb with Odbc

I am trying to connect my web application to an old MS Access mdb file.
I found this page:
https://learn.microsoft.com/en-us/dotnet/api/system.data.odbc.odbcconnection?view=dotnet-plat-ext-6.0
But I can't figure out how to work with connection strings, I keep getting the Error:
'ERROR [08001] [Microsoft][ODBC Driver 18 for SQL Server]MAX_PROVS: Error Locating Server/Instance Specified [xFFFFFFFF].
ERROR [HYT00] [Microsoft][ODBC Driver 18 for SQL Server]Login timeout expired
ERROR [01S00] [Microsoft][ODBC Driver 18 for SQL Server]Invalid connection string attribute
ERROR [08001] [Microsoft][ODBC Driver 18 for SQL Server]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.'
https://www.connectionstrings.com/microsoft-odbc-driver-17-for-sql-server/
Found this page, although I have the 18 driver installed it should only change the 17 -> 18.
My current Connection string looks like this
Driver={ODBC Driver 18 for SQL Server}; Server=.\SQLExpress; AttachDbFilename = D:\temp\datacollector\microfas.mdb; Trusted_Connection=yes;
But I have no idea if I am approaching it the right way. The application will eventually run locally at a customer with a known location of the .mdb file.

Entity framework - The provider did not return a ProviderManifestToken string error

I am using SQL Server 2005 Express with SQL Servre authentication and remote connections enabled although I am working locally.
My web.config connection string part:
<add name="HelpDesk2connect" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string='Data Source=SATURN;Initial Catalog=HelpDesk2;Integrated Security=False;user id=sa;password=*******;multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />
I am logging in as sa
In the controller I get these errors (in this statement: `return View(db.Tickets.ToList());)
An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.
The provider did not return a ProviderManifestToken string.
In the page I get this error:
[SqlException (0x80131904): 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: SQL Network Interfaces, error: 52 - Unable to locate a LocalDB installation. Verify that SQL Server Express is properly installed and that the LocalDB feature is enabled.)]
Can you help me spot what am I doing wrong?
Thanx in advance
