EN node not syncing

[aki263]

I downloaded latest EN snapshot as mentioned in https://docs.klaytn.foundation/docs/nodes/endpoint-node/docker-setup/.

Running this in ec2 instance that is in private subnet and has a nat gateway.

NETWORK="cypress"
NETWORK_ID="8217"
SERVER_TYPE="http"
SYNCMODE="full"
VERBOSITY=4
RPC_ENABLE=1
RPC_API="admin, debug, klay, miner, net, personal, rpc, txpool, web3"
RPC_ADDR="0.0.0.0"
RPC_VHOSTS="*"
WS_ENABLE=1
WS_API="admin, debug, klay, miner, net, personal, rpc, txpool, web3"
METRICS=1
PROMETHEUS=1
DATA_DIR=/var/kend/data
LOG_DIR=/var/kend/logs
ADDITIONAL="--upstream-en https://archive-en.cypress.klaytn.net"

Now I am getting error for new data to sync

Could you share the output of ps -ef | grep ken? In addition, the level of the log you shared is debug level which is not an error. Can you share the entire log? (from the latest start to the current) Btw, have you checked the connection configurations and ken version? (static-nodes.json, NO_DISCOVERY option on kend.conf which will be converted into --nodiscover flag)

You mentioned you are running in the private subnet. Please check the opened ports. For the node connection, you should open the node ports. The default port of klaytn node is 30303,30304 unless you configure your own klaytn node port.
