LocalHost Refused to Connect ( Urgent Help)

Hi People ,

I really require an advice asap, my traccar service is running, but when i'm trying to run the localhost:8082 it says refused to connect.

This was not happening before, it just started to happen now.

I recently modified the traccar.xml file with my SQL configurations.

<entry key='database.driver'>com.mysql.jdbc.Driver</entry> 
<entry key='database.url'>jdbc:mysql://localhost:3306/traccar?serverTimezone=UTC&amp;useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>
 <entry key='database.user'>root</entry> 
 <entry key='database.password'>Omarzoha2014.</entry>

Over here "traccar" is the name of the database I created in the connection test which has the user root and password Omarzoha2014.

My log file shows:

Does anybody know what could be the reason for the refused connection ?

Urgent help required.

Please never duplicate your questions between multiple threads.

Sorry Anton about it.
Can you please let me know a solution for the above problem.

Try this
<entry key='database.driver'>com.mysql.cj.jdbc.Driver</entry>

Dear all,
Any help please, I installed openGTS and I want to integrate traccar in it, I had already installed and I configured the traccar.xml file as you can show here:

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'>

<properties>

    <entry key='config.default'>./conf/traccar.xml</entry>

</entry>

<entry key='database.insertPosition'>
    START TRANSACTION;
        UPDATE Device SET lastValidLatitude = :latitude, lastValidLongitude = :longitude, lastGPSTimestamp = UNIX_TIMESTAMP(:fixTime), lastUpdateTime = UNIX_TIMESTAMP(NOW()) WHERE imeiNumber = SUBSTRING(CAST(:deviceId AS CHAR(32)), 2);
        SELECT @accountID := accountID, @deviceID := deviceID FROM Device WHERE imeiNumber = SUBSTRING(CAST(:deviceId AS CHAR(32)), 2);
        INSERT INTO EventData (accountID, deviceID, timestamp, statusCode, latitude, longitude, speedKPH, heading, altitude, rawData, creationTime, address)
        VALUES (@accountID, @deviceID, UNIX_TIMESTAMP(:fixTime), 0, :latitude, :longitude, :speed * 1.852, :course, :altitude, '', UNIX_TIMESTAMP(NOW()), :address);
    COMMIT;
</entry>

</properties>

When I restart the traccar server and look at the tracker-server.log I got error message as follow:

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
