+## SkipSsl in MySQL/MariaDB database connection
+set the value of `dump.skip_ssl` to `true`  in your `config/database.php` to bypass **`TLS/SSL error: self-signed certificate`** error while establishing a database connection
+
+Here's an example for MySQL:
+
+```php
+//config/database.php
+'connections' => [
+	'mysql' => [
+		'driver'    => 'mysql'
+		...,
+		'dump' => [
+                    'dump_binary_path' => '/path/to/the/binary', // only the path, so without `mysqldump` or `pg_dump`
+                    'skip_ssl' => true, // default value is `false`
