I have created 2 droplets one for my frontend and another for my backend.
I have linked both of them using the IP Address.

But When I am trying to make get request using Postman.
It is throwing this error:

Error -> SequelizeConnectionError: Client does not support authentication protocol requested by server; consider upgrading MySQL client

And when I am trying to access it from my vue.js application.
It is throwing this error:
net::ERRCONNECTIONREFUSED

Please help
