Getsockopt: connection refused ipfshttp.go when run ipfs cluster in ubutu 16.04

I created a private ipfs cluster in ubuntu 16.04, but when i run peers, it notification error:

18:21:50.343 ERROR ipfshttp: error getting:Get dial tcp getsockopt: connection refused ipfshttp.go:695

Can you help me ?

It would seem you are not running IPFS (if you are starting both a the same time this error may occur (since ipfs takes a while longer to boot up, but is not critical).

thank you, it worked
