Hi there @akusit,

What is the exact error that you get? Also are you using MySQL or any other SQL service?

It sounds like your MySQL service might not be running. You can check this with the following command:

sudo systemctl status mysql

If this is the case, you can start MySQL with the following command:

sudo systemctl start mysql

To prevent this in the future make sure to enable MySQL to start on boot:

sudo systemctl enable mysql

Let me know how it goes.
Regards,
Bobby
