Why does this error happen?

This can happen for a variety of different reasons. Possible reasons include:

  • A firewall rule on your network could be blocking traffic.
  • Your ISP has strict firewalls you are not aware of. Call your ISP to confirm.  
  • Your antenna is in a non-optimal location or you are using a non-optimal antenna.
  • You have the miner deployed in the wrong region. (AU915, US915, EU868, etc). 
  • There are too few miner’s in your area or not enough of the nearby miners are functional.
  • You are experiencing a network packet forwarding bug.

What you can try
1. First try Rebooting your hotspot
2. Try moving your hotspot to the DMZ in your router's settings or disabling firewall rules applied to the hotspot
3. Try refining your antenna setup by swapping to a more optimal antenna and/or getting it high up and outside if possible, the more line of sight around the antenna the better
4. Try moving miner/antenna to a different location to test
5. Move the antenna outside to a higher, more visible location
6. Double check with your ISP to see if there is a strict firewall.
What to provide customer support if unable to resolve
1. Confirm you have adjusted your firewall settings. If you have configured pass packet rules in your internet router, please indicate if you have confirmed that these were done correctly.
2. Describe where exactly your antenna is located. Is it inside/outside, on the roof, in a window, on a pole, under a tree, near a building, near a hill? Please be specific.
3. What type of internet service is the miner using, for example: Mobile, Hotspot, Broadband, Cable, DSL Satellite, Fiber Optic…
4. Provide more details about your Network set up, are you on a mesh network, are there additional miners on that network, are you using a VPN, IPV4, IPV6…
