It would appear that the Electron Cash server you are connected to is unable to find any unspent BCH outputs for that address. It's quite possible, that your Electron Cash wallet is connecting to a BTC server (ElectronCash is a bit flaky like that)... you may want to untick AutoConnect and select one manually... look for the servers that specify BCC in the name.
After selecting a BCC server, you may need to shutdown ElectronCash, delete the blockchain_headers file from the EC datadir and restart ElectronCash and then wait for a few minutes for it to sync up...

Can you please suggest reliable BCC server?
