Hyperledger explorer is unable to connect to the network - hyperledger-fabric

Question

I have my network up and running. When I try to connect the same with the latest explorer it throws the following error.
config.json: looks like:

I am not sure what is the 'client-1' should be give. When I run the ./start.sh inside the blockchain-explorer root. I am getting this logs.
