Terminal, upgrade and control conflicts

Use the exact session or update stage to narrow the fault.

Terminal

• Confirm the session is ready, Client is connected and the share link is not revoked or expired.
• If the browser is connected but no PTY appears, inspect terminal relay and Client logs.

Upgrade

• Check free space and the artifact stage rather than treating every failure as a network error.
• Verify the installed binary architecture, checksum and version after the switch.

Control conflict

• Identify every controller and choose a single owner before restarting MINER processes.
