1. Check node version
Make sure your node is up to date.
Outdated versions can cause connection issues.
2. Identify the type of issue
Connection problems usually fall into one of these:
Can’t connect at all
No sessions established
Status shows Monitoring failed
Often caused by Strict / Symmetric NAT
Can connect but no internet access
Session starts but browsing fails
Usually caused by DNS or firewall issues
Poor connection quality
Slow speeds, disconnects
Often network or ISP related
3. Run a connection test
From your MystNodes dashboard:
Open node dashboard
Click the three dots menu
Select Test node
Expected:
A session appears in NodeUI
Status changes to Online in sometime
If not, Status remains Monitoring failed
4. Check NAT type
Run:
docker run -it --rm yarmak/natdisco
Expected: Open or Moderate NAT
If you see: Strict / Symmetric NAT → connections will fail
5. Fix NAT and connectivity
Enable UPnP
Enable in router settings
Restart node
Port forwarding
Forward UDP ports:
56000 - 56100Assign a static IP
DMZ (last resort)
Assign your node host to DMZ
Use carefully (reduces network security)
6. Check firewall and system configuration
If connections are attempted but not completed, your firewall or system configuration may be blocking traffic.
Ensure UDP traffic is allowed
Ensure required ports are open
Check that forwarding is not restricted
For detailed steps, see:
7. Retest after changes
Restart node
Run Test node again
Check if sessions appear
