Asked by harshitttpandey
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::ERR_CONNECTION_REFUSED
Please help

Hello,
Are you using the new DigitalOcean Managed MySQL service? If so you might have to create a new user with authentication type
mysql_native_passwordor alter your doadmin user so that it does not use zcaching_sha2_passwordz butmysql_native_password. That way your node should be able to connect to the MySQL database.You can take a look at this answer here on how to do that:

Also, I would recommend testing if you could connect from your backend droplet to your MySQL server using telnet:
If the telnet command connects you fine, then it is not an issue with your firewall, so I would recommend that you share your config files here so that I could advise you further.
