Ubuntu phpmyadmin does not match correct password HOW?

Question

PHP

I installed phpmyadmin on Ubuntu 16 through the console mysql -u root -p, authorization passes through, but not through phpmyadmin.
In the config, access without a password is allowed.
$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

How is this even possible? After all, if it enters through the console, then the password is correct.

Answer 1

Check the access rights for the root, first of all, on which IP he is allowed to enter.
Usually it's easier to look in the logs for what reason the refusal came
