How to connect a new peer in both command and webui

I have given below for connecting a peer

ipfs swarm connect /ip4/

Error: connect QmZBrRsfqsiy2faB3Q2cr5dqwBCy51VtxXVxBGoQ3RBTRV failure: dial attempt failed: 1 error occurred:
* <peer.ID QmGkd4KN> --> <peer.ID Qm3RBTRV> (/ip4/ dial attempt failed: dial tcp4> i/o timeout

It looks like that node is refusing all new connections.
