Host 'localhost' is not allowed to connect to this MariaDB server

[Ridhwan Ginanjar]

I have a problem accessing the database today (yesterday not), this happened the second time but at that time I forgot to fix it because it did not want to reinstall laragon.

Laragon I use: Laragon Full 3.1.8.171220

php-7.2.10Win32-VC15-x64
Apache httpd-2.4.29-Win64-VC15 80/443
MariaDB mariadb-10.2.11-winx64 3306

Is there a way to fix this? thanks for helping me

@Ridhwan-Ginanjar : Any error message?
Note: You can restore MariaDB yourself:

1. Rename data to data.bak
2. Click "Start All" - Laragon will re-generate new clean data
3. (Optional) Now MariaDB is running, you can restore from backup or migration

I had analogical problem because my pc lost power and something in maria db crashed. I have a lot work on local so i wanted to try to fix it instead restore/create fresh db. I did it so i would to share with my solution:

Go to mariadb bin folder for example:
C:\laragon\bin\mysql\mariadb-10.2.13-winx64

Find my.ini and open.
Simply add single line:
skip-grant-tables
after [mysqld] group.

Example:

...
[mysqld]
skip-grant-tables
port=3306
socket=/tmp/mysql.sock
...

Now we are able to enter to mysql and phpmyadmin, in my case i use phpmyadmin and i get many errors on home page about crashed user table so i run SQL queries:

USE mysql;
CHECK TABLE user;
REPAIR TABLE user;

And voilà. Now we can remove skip-grant-tables just in case.
