Olá, Danilo

Esse erro geralmente ocorre quando a aplicação não consegue estabelecer uma conexão com o servidor MySQL. Existem algumas possíveis causas para esse problema:

Certifique-se de que o servidor MySQL está em execução e acessível. Verifique se o endereço do servidor, a porta e as credenciais de acesso estão corretos.
Verifique se você tem permissão para acessar o servidor MySQL a partir da sua máquina. Alguns servidores MySQL podem ter restrições de acesso baseadas em IP ou usuário.
Verifique se o banco de dados que você está tentando acessar existe e está configurado corretamente. Certifique-se de que o nome do banco de dados, o usuário e a senha estão corretos.
Verifique se o driver MySQL Connector/NET está instalado corretamente. Você pode tentar reinstalá-lo ou atualizá-lo para a versão mais recente.

Além disso, é sempre uma boa prática verificar se há algum firewall ou software de segurança que possa estar bloqueando a conexão com o servidor MySQL.

Espero que essas dicas possam te ajudar a resolver o problema de conexão com o banco de dados. Se você tiver mais alguma dúvida, é só me dizer.

Espero ter ajudado e bons estudos!
