error message to connect my database

Hi,

I'm currently working on a project where I'm collecting data from an antenna and saving it to a text file. However, I'd like to have the data organized more efficiently and store it in a database. I've already designed the database, but when I try to transfer the received data to the database using a Python script, I get the following error message:Error connecting to database: connection to server at "localhost" (::1), port 3306 failed: expected authentication request from server, but received Y

i dont know to resolve it, please anyone can help me?
