Fix SFTP Public Key Authentication Errors — Resolve SSH Issues with RcloneView
SFTP public key authentication failures are almost always caused by key path, file permission, or passphrase mismatches — this guide walks through each one systematically.
SFTP is one of the most common ways to connect remote Linux servers in RcloneView, and public key authentication is the preferred security method over passwords. When key auth fails, the errors can be cryptic: ssh: handshake failed, permission denied (publickey), or no supported methods remain. This guide covers the most frequent causes and how to diagnose and fix each one.
