Cannot Access SQL Server to Connect Database - sql-server

I have created a database on our SQL Server for Eplan. When I try to login to SQL using Windows Authentication I receive an error that states:
Login Failed. Login is from an untrusted domain and cannot be used with Windows authentication.
When I use my SQL server login it returns:
Connection could not be established. Login failed for user xxx
So I've verified that I am using the correct login/password. TCP/IP is enabled and SQL Server uses SQL Server and Windows Authentication.
I am really at loss as to what to do next.
Thank you!

Cannot connect to server after creating a logon and user

I've been having troubles in creating new users on the SQL Server. Those were the steps I took:
Connect to the server via Windows authentication
Access Security > Logons > Create Logon
Create a new Logon to use SQL Server authentication
In each database, create new users (same name as logon). Those users were set Owned Schemas and Membership as db_datareader and db_datawriter
Close the connection and connect by the user created
After that process, I get the message:
It is not possible to connect to DESKTOP-QMQIHKL:
A connection with the server was successfully establishes, but during the logon process an error occurred. (provider: Shared Memory Provider, error: 0 - There is not a process in the other extreme of the pipe). (Microsoft SQL Server, Error: 233).
I've tried to overcome this error message by:
Opening SQL Server Configuration Manager and enable the TCP/IP protocol.
Opening Windows Services and executing both, SQL Server Browser and SQL Server (MSSQLSERVER).
None of that have worked. For that reason, I would like your help in solving this problem.
Have you enabled SQL Server authentication mode? By default, SQL Server is configured to use exclusively Windows authentication mode, so it will not accept your SQL Server authentication logins.
For changing the accepted authentication modes, see this article: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/change-server-authentication-mode?view=sql-server-ver15

Can't Login to SQL Server with SQL Server Management Studio

So I've been working with SQL Server 2017 Developement for a few hours now.
I set up that I can connect via SQL Server Authentication;
I enabled my SA and I created a new Login.
both were setup properly by standards (Rights to databases etc)
Now I want to use SQL Server Management Studio to login via SQL Server Authentication but I get this error
(it says sa now but its the same whether it is sa or my created login)
TITLE: Connect to Server
------------------------------
Cannot connect to ..

ADDITIONAL INFORMATION:
Login failed for user 'sa'. (Microsoft SQL Server, Error: 18456)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft%20SQL%20Server&EvtSrc=MSSQLServer&EvtID=18456&LinkId=20476

I have "Encrypt connection" & "Trust server certificate" enabled in my options
I have search google for a solution but the only solution to my error is that I need to enable "Trust server certificate" but it doesn't resolve my problem.
Thanks in advance
Please check the Server authentication mode, in the service configuration choose the SQL Server and Windows Authentication mode radio button and Restart SQL Services.

SQL Server 2016 Remote Connection Error 18456

I have recently installed SQL Server 2016 on Amazon EC2 instance so I can start developing various SSIS / SSRS applications.
I have enabled Remote connections, opened port 1433 in the security group and windows firewall, and created a user 'myuser123' who is enabled and and allowed SQL Server and Windows Authentication within the server properties.
I am trying to login using this connection
ec2-1-2-3-4.eu-west-1.compute.amazonaws.com\MSSQLSERVER,1433
SQL Server Authentication
username: myuser123
password: #########
The error message I am getting looks to be a user authentication error.
Cannot connect to ec2-1-2-3-4.eu-west-1.compute.amazonaws.com\MSSQLSERVER,1433
Additional Information
Login failed for user 'myuser123'. (Microsoft SQL Server, Error 18456)
However when I Remote Desktop to the EC2 Instance and try to log in locally using the same username / password I don't have any problem.
Do you have any idea why this may be?
Thanks

Remote connection to SQL Server 2012 Express

To clarify this in the start. I don't have much experience with SQL Server so every help will be appreciated.
I have a task to set up some program with a SQL Server Express database which is located on a remote server. The database is, as far as I know, configured and should be working. This is the information I have to connect to the database:
IP: xx.xxx.xxx.xxx
The administrator password is 'somepassword'
The SA password is 'anotherpassword'
I think this info is incomplete because there is no username. But what worries me is that I don't get feedback that my password or username are incorrect. Instead I get the error:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server...
I'm using SQL Server Management Studio to connect to the database (SQL Server 2012 Express) and I added an exception in firewall for Management Studio.
And what is the difference between administrator and SA (system administrator) password?
The message you are receiving basically means "I can't connect to SQL Server". It can be due to a number of issues:
The SQL Server service is not running
The SQL Server instance is not configured to use TCP/IP to communicate
The database is using windows authentication and the user is not authorized or
The database is using mixed-mode authentication and the user/pass is incorrect
As for the usernames you are given, I would assume that the "administrator" username is local windows administrator of the machine SQL server is running on, and that the "sa" user is the default database administrator, that is installed when setting SQL Server to use mixed-mode authentication.
So, I would recommend to try connecting to the database using Mixed-mode authentication, with the username "sa" and the "anotherpassword" password.

SQL server 2008 login issue

Hi I created a new login SQL server authentication in SQL server 2008, however I am unable to login with that user.
Getting an error like ,
TITLE: Connect to Server
Cannot connect to (local).
ADDITIONAL INFORMATION:
Login failed for user 'sa'. (Microsoft SQL Server, Error: 18456)
The error Login failed for user 'sa' means that connection to server was established, but server refused it under certain circumstances, such as:
Wrong password
Sql server uses only Windows Authentication (needs server restart)
In your Connection String you ask to connect to specified DB, which is not exists
sa login is Disabled or Denied to access sql engine
User Action
If you are trying to connect using SQL Server Authentication, verify
that SQL Server is configured in Mixed Authentication Mode.
If you are trying to connect using SQL Server Authentication, verify
that SQL Server login exists and that you have spelled it properly.
If you are trying to connect using Windows Authentication, verify
that you are properly logged into the correct domain.
If your error indicates state 1, contact your SQL Server
administrator.
