Hi, I need some help with a MySQL JDBC connection issue that I've been struggling with for the past 3 months. I’ve tried almost everything. **org.springframework.jdbc.cannotgetjdbcconnectionexception: failed to obtain jdbc connection after some time** MySQL version: 8.0.42 Driver: I tried both mysql-connector-java-8.4.0 and 5.1.48 Java: Using Corretto 21 OS: Windows 11 IDE: IntelliJ and Eclipse (same issue) MySQL service is running Credentials are correct (I can log in with the same root user and password using MySQL CLI and Workbench) Still, in Java, it throws: org.springframework.jdbc.cannotgetjdbcconnectionexception: failed to obtain jdbc connection after some time. java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) Things I’ve tried: ✔ Verified user privileges ✔ Reinstalled MySQL multiple times ✔ Tried different drivers ✔ Disabled sleep/hibernate ✔ Rechecked JDBC URL with useSSL=false&allowPublicKeyRetrieval=true ✔ Even tested with plain JDBC code — same result ✔ Restarted laptop and MySQL many times I’m really stuck and losing a lot of time due to this. If you’ve experienced this or can guide me, it would mean a lot 🙏 -- This is an automated message from the Apache Git Service.
