I started to get this error after upgrading the engine to 4.18.1
ERROR: Failed to run init commands on 192.168.25.107. Output = Permission denied (publickey,password,keyboard-interactive).
Tried this answer solution but no good: PC to iMac - Remote Build Fails : Failed to run init commands on 192.168.0.6. Output = Permission denied (publickey,password,keyboard-interactive) - Platform & Builds - Unreal Engine Forums
anyone know what could be?
