Hyperledger Fabric Explorer set up issue

Question

I have set up my fabric network by official tutorial. Now I want to set up my first Fabric Explorer.

I follow this tutorial(docker version): https://github.com/hyperledger-labs/blockchain-explorer I set up my config well, and docker-compose up -d is good as well,

$ docker-compose up -d
Creating explorerdb.mynetwork.com ... done
Creating explorer.mynetwork.com   ... done

but when I check my explorer by '127.0.0.1:8080'. It doesn't work. and I check my docker container. My 'explorer.mynetwork.com' container status is Exited (1) About an hour ago

and there is a error in the log is

$ docker logs explorer.mynetwork.com

\[ERROR\] FabricGateway - Failed to create wallet, please check the configuration, and valid file paths
{
"errno": -2,
"code": "ENOENT",
"syscall": "open",
"path": "/tmp/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
}
[2023-08-31T07:46:01.623] [ERROR] FabricClient - ExplorerError {
  name: 'ExplorerError',
  message: '[\n' +
    "  'Failed to create wallet, please check the configuration, and valid file paths'\n" +
    ']'
}
