What problem does it solve? Managing a cluster of 3x-ui proxy panels requires correctly adding nodes, choosing TLS trust modes, syncing inbounds selectively, and monitoring node health — mistakes here cause outages or security gaps. This Skill provides the verified procedures for operating a multi-panel 3x-ui cluster safely. ## Core Features & Use Cases - Safe node onboarding: Probe connectivity with test_node before saving, then add nodes and choose between full or selective inbound sync by tag. - TLS trust management: Configure verify, skip, pin, or mTLS trust modes, pin certificate fingerprints, and set up mutual TLS between master and node panels. - Cluster operations: Monitor node health and per-node traffic history, pause sync for maintenance, and roll out panel updates in a controlled order. - Use Case: You run three 3x-ui servers and want one master panel to push client configurations to the others. Use this Skill to probe each server, pin its self-signed certificate, sync only the relevant inbound tags, and watch per-node traffic. ## Quick Start Add the server at node1.example:2053 as a node of this 3x-ui panel, probe it first, then pin its certificate and sync only the selected inbound tags.
