Can't connect to MySQL with DataGrip via unix socket

it's my first time using DataGrip trying to connect to MySQL in a Ubuntu 18.04 server.
I've added a new user to MySQL. When I try to connect to MySQL using the command MySQL -u user -p works.
But on DataGrip, I've created an ssh tunnel and it's making the connection without any problems.
But when trying to connect to MySQL it gives this error The specified database user/password combination is rejected: [28000][1698] Access denied for user 'user'#'localhost'.
I am sure that the password is correct and in the log file it is showing that it's making the ssh connection, but it gives access denied when connecting to MySQL. If someone could help me, I appreciate it.
To connect to MySQL server using unix sockets follow an article in DataGrip documentation.
Connection via sockets available in DataGrip since version 2021.1.

MySQL said: Can't connect to MySQL server on '127.0.0.1' (4)

the above problem has few solutions here but I couldn't get any of them working so asking.
I have installed mamp and also sequel pro. I am trying to connect using sequel pro but I am getting this error. The whole error is
Unable to connect to host 127.0.0.1, or the request timed out.
Be sure that the address is correct and that you have the necessary
privileges, or try increasing the connection timeout (currently 10 seconds).
MySQL said: Can't connect to MySQL server on '127.0.0.1' (4)
This is the first time I am trying to connect via standard connection.
I tried socket connection it works but I cannot connect the database with my nodejs application. Thanks
I had same experience using Sequel Pro.
Go to Preferences (Sequel Pro) => Network and increase the timeout seconds to maybe 30.
That solved my issue.

Can't connect StrongLoop with AWS RDS MySQL instance

I setup an AWS RDS MySQL instance and was able to connect to it successfully using MySQL Workbench.
However when I use StrongLoop Arc to Test Connection to this MySQL instance using the same credentials, I keep getting a Handshake inactivity timeout error.
Any idea why MySQL Workbench can connect to this MySQL instance but StrongLoop can't?

mySQL command line works but ODBC and workbench do not

I am trying to test a connection to a mySQL database running on a remote linux server. I am running Windows 7 and have mySQL installed on my machine as well as the 32-bit ODBC driver. I can connect from the DOS command prompt with no problems. But I cannot connect using mySQL workbench or with ODBC (from MS Access).
In MySQL workbench my error is:
Your connection attempt failed for user 'username' from your host to server at 'x.x.x.x:x': Unknown MySQL server host 'x.x.x.x' (0)
In MS Acess (ODBC driver) my error is:
Connection faile:[HY000][MySQL][ODBC 5.2(w) Driver]Can't connect to MySQL server on 'x.x.x.x' (10061)
I've searched stackoverflow extensively and I found lots of people who can't get ANY connection to work. But I know I can log in from my computer. Could it be something other than ports?
Please make sure you are using correct ip address in MySQL workbench to connect to your mysql database
