DEBUG[09-17|02:27:35.307] ENR request failed id=7498feef0de4a2e6 addr=@ip:30312 err="invalid IP in response record: loopback address from non-loopback host"

  • I think, any of the deployed geth nodes is using non-loopback address and other one is using loopback address. When bootnode gets a request of findNode and handles it, it finds that one is loopback and another one is non. So, it gives the error response. – Md Rayhanul Masud Saom Sep 18 '19 at 4:25

You need to enable UDP rule for port 30310 for ec2 instance running bootnode.

  • i just realise when i use bootnode -nodekey boot.key -verbosity 9 -addr :30310 command to setup bootnode it gives self=enode://somenode@127.0.0.1:30310 .. that 127.0.0.1 is problem i guess. also i tried using bootnode -nodekey boot.key -verbosity 9 -addr 0.0.0.0:30310 still 127.0.0.1 remains same – ash Sep 28 '19 at 14:35
