Recommended action: On the SSH host add 'AllowTcpForwarding yes' to /etc/ssh/sshd_config (or C:\ProgramData\ssh\sshd_config) and restart sshd; if you cannot change sshd, ask the administrator. Option: Enable AllowTcpForwarding on the SSH host [evidence: official_recommended_action] Applies when: You control the host sshd Steps: 1. Edit /etc/ssh/sshd_config on the host 2. Add AllowTcpForwarding yes 3. sudo systemctl restart sshd (Windows: Restart-Service sshd) 4. Retry connection Expected: Tunnel opens and the remote window connects. Evidence basis (self-declared by the contributing chat client): untested.
