How to Fix Rustdesk Not Ready Please Check Your Connection?

What causes the Rustdesk Not Ready Please Check Your Connection error?

The message “Rustdesk Not Ready Please Check Your Connection” usually appears when the app cannot connect to the Rustdesk relay or rendezvous server. This problem often comes from network or firewall settings, server issues, or incorrect configurations. In most cases, it may be due to a poor internet connection, blocked ports, or wrong self-hosted server details.

To start troubleshooting, first make sure your internet connection is stable. Restart your modem or router to clear any temporary network errors. If the problem continues, try connecting through another network, such as a mobile hotspot, or switch from Wi-Fi to a wired connection. Also, check whether your firewall or antivirus is blocking Rustdesk’s ports (21115–21119). If you are using a custom server, confirm that the relay and rendezvous addresses and keys are correct.

In short, this error usually points to a network or configuration issue that prevents Rustdesk from communicating with its server.

How to fix the Rustdesk Not Ready Please Check Your Connection issue?

If you keep seeing the “Rustdesk Not Ready Please Check Your Connection” message, there are several ways to fix it depending on the cause. The problem may come from your network, firewall settings, or server configuration. Below are five practical methods you can follow step by step to identify and resolve the issue effectively.

Fix 1. Check Server and Port Configuration

If the message “Rustdesk Not Ready Please Check Your Connection” appears while using a self-hosted setup, your server might not be running correctly. Rustdesk depends on the hbbr (relay) and hbbs (rendezvous) servers to handle connections.
Step 1. Log in to the server and confirm both hbbr and hbbs services are running properly.
Step 2. Make sure the correct server IP address or domain name is entered in the Rustdesk client.
Step 3. Test if the server ports are open by running a command like telnet 21116 or by pinging the server.

Fix 2. Verify Firewall and Port Forwarding

A common cause of the “Rustdesk not ready” message is blocked ports. Firewalls or routers may prevent Rustdesk from connecting to its servers.
Step 1. Open your firewall settings and allow Rustdesk through both inbound and outbound rules.
Step 2. Make sure the following ports are open:

• TCP: 21115–21119, 8000

• UDP: 21116

Step 3. If you use a router, configure port forwarding for these ports to your Rustdesk server’s local IP address.

Fix 3. Address NAT Loopback Problems

If Rustdesk connects from an external network but not from your local one, your router might not support NAT loopback, which causes local devices to fail when connecting to the public IP.
Step 1. Test Rustdesk on a mobile hotspot or external network to confirm the connection works outside your LAN.
Step 2. Inside your local network, try connecting using the local IP instead of the public IP.
Step 3. If the issue remains, enable hairpin NAT or set up internal DNS rules on your router to map the hostname to the local IP.

Fix 4. Check VPN and DNS Settings

VPNs and custom DNS services can interfere with Rustdesk’s ability to reach the relay or rendezvous server.
Step 1. Turn off your VPN and check if the Rustdesk connection works.
Step 2. If a VPN is required, allow local network access or whitelist Rustdesk in the VPN settings.
Step 3. Change your DNS to a reliable option like Google DNS (8.8.8.8 / 8.8.4.4) or Cloudflare DNS (1.1.1.1) to fix DNS conflicts.

Fix 5. Update the Rustdesk Client

An outdated Rustdesk version can also cause connection errors or compatibility problems. Updating often fixes known bugs and improves server connectivity.
Step 1. Go to the official Rustdesk website or GitHub page.
Step 2. Download and install the latest version of the client for your operating system.
Step 3. Restart Rustdesk and check if the “Rustdesk Not Ready Please Check Your Connection” error disappears.
