I am trying to setup the Hyperledger Explorer to work with my fabric network. I managed to bring up the explorer without using docker, but when I try to bring up the explorer in docker using docker-compose. I am facing below error in explorer.mynetwork.com container. I have provided correct value for CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051 in the peer container configuration. I followed https://github.com/hyperledger/blockchain-explorer documentation for the docker setup. Please let me know if I missed any configuration.

First of all, I recommend trying to use explorer docker images with fabric-samples/first-network.
# After bringing up fabric-samples/first-network
# Copy artifacts into the path which is mounted on explorer container
$ cp -a /some/where/fabric-samples/first-network/crypto-config/* examples/net1/crypto/
# Edit connection profile to change secret key file name
$ vi examples/net1/connection-profile/first-network.json
$ git diff examples/

# Pull the latest container images (v0.3.9.5)
$ docker pull hyperledger/explorer
$ docker pull hyperledger/explorer-db
# Make sure the persistant volumes removed
$ docker-compose down -v
# Bring up containers
$ docker-compose up -d explorerdb.mynetwork.com
$ docker-compose up -d explorer.mynetwork.com
# Access http://localhost:8090
After making sure explorer is working fine in this environment, please\ modify configuration (connection profile) to align to your own fabric network.
