i am trying to create private POA network in which i have 3 aws ec2 ubuntu servers. on 1st server bootnode and on 2nd server POA node1 is running and on 3rd server POA node 2 running. but i am not able to connect the node1 and node2 also bootnode shows this error when i tried to just node2 to connect to

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. Sep 18, 2019 at 4:25

  • i just realise when i use bootnode -nodekey boot.key -verbosity 9 -addr :30310 command to setup bootnode it gives self=enode://[email protected]:30310 .. that is problem i guess. also i tried using bootnode -nodekey boot.key -verbosity 9 -addr still remains same
