Your problem is with `zmqpubrawtx`

    zmqpubrawtx=tcp://127.0.0.1:28332
    zmqpubhashblock=tcp://127.0.0.1:28332

Remove them and see if it will work.

### Answer by username_0 on 2018-05-03. Score: 1

I solved this issue,

Actually it was issue related confliction because I have setup more than one currency in single server Like (Bitcoin, litecoin & zcash)

For that, I have taken care rpcport & change port for "zmq" in config file and then it is working fine.

Config:

```
server=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
zmqpubrawtx=tcp://127.0.0.1:28334
zmqpubhashblock=tcp://127.0.0.1:28334
rpcport=8334
rpcallowip=127.0.0.1
rpcuser=YANNISCOOLUSER
rpcpassword=YANNPASSISCOOL
uacomment=bitcore
listen=0

```
