Connection Troubleshooting

Tips for resolving local socket, network, and file permission configurations.

Connecting to Local PostgreSQL (Port 5432)

Issue: Connection refused on localhost or 127.0.0.1

Ensure PostgreSQL service is running in Windows Services (services.msc). Verify that pg_hba.conf allows local authentication for 127.0.0.1/32.

Connecting to Local MySQL (Port 3306)

Issue: Access denied for user 'root'@'localhost'

Ensure the MySQL user has privileges on host '127.0.0.1' or '%' rather than solely Unix sockets. Check that MySQL service is listening on TCP port 3306.

Working with SQLite & DuckDB Files

Issue: File locked by another Windows process

SQLite and DuckDB open direct local file handles. Ensure other external programs or background sync tools are not locking the .db or .duckdb file during write transactions.

SSH Bastion Tunneling Authentication

Issue: SSH handshake failure or key format error

Lopo Studio supports OpenSSH standard private keys and password authentication. Database passwords and SSH key passphrases are stored in Windows Credential Manager.
