No Mysql Backup mysqldump: Got error: 1045: Access denied for user 'root'@'localhost' (using password: YES) when trying to connect

Hello,

i have installed traccar with https://www.traccar.org/install-digitalocean/

When i try a backup mysq: root@gps02:~# mysqldump -u root -h localhost -p traccar > traccar.sql
Enter password:

i receive this error:
mysqldump: Got error: 1045: Access denied for user 'root'@'localhost' (using password: YES) when trying to connect

i can login on the virtual server with root, the login on mysql is not working

How can I backup the Traccar Database?

Thank You?

Are you sure you're using the right password?

If, when you installed MySQL, you did not secure it, then the root password is possibly blank!
If you secured it, then use the correct password.

I have found the error. The password is root. Many thanks for your help!

What did you use?

User root Password root

No, I meant before.

the root password for the vm
