Updating 'Allowable hosts'
Also, make sure that your current IP address is added to the database's allowable hosts. You can manage this setting on the MySQL Databases page.
To the right of your database, click the username. On the next page you can see the 'Allowable hosts' field.
In the image above, you would replace xxx.xxx.xxx.xxx with your computer's IP address. You can find it on a site such as whatismyipaddress.com. The panel also displays your current IP address in this section.
Reboot the server
Due to the nature of shared MySQL hosting, it's not possible to reboot your MySQL server. The only way this would be possible is if you were on a Dedicated Hosting plan. On a Dedicated Server, the MySQL server is hosted on the same machine allowing you full root access.
"Loading local data is disabled; this must be enabled on both the client and server sides"
This error can occur when using the LOAD DATA LOCAL INFILE statement to load data into a MySQL 8 database. A change to the default settings introduced in MySQL 8 no longer allows local data to be loaded, for security purposes.
It is possible to load data using an alternate method. See the MySQL Overview page for more details.
