Get the error:Error: proposal failed (err: bad proposal response 500) when I try to join a peer to an existed channel?

问题

I tried to get the newest block from an exist channel by:

peer channel fetch newest mychannel.block -c mychannel --orderer orderer.zee.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/zee.com/orderers/orderer.zee.com/msp/tlscacerts/tlsca.zee.com-cert.pem

then I got mychannel.block in current directory. Using this block I applied

peer channel join -b mychannel.block --orderer orderer.zee.com:7050\

I expected to join that channel(before that I already checked this peer is not in the channel list by call peer channel list). But an error printed out:
