How to connect a new peer in both command and webui

#1

I have given below for connecting a peer

ipfs swarm connect /ip4/104.131.131.82/tcp/4001/ipfs/QmZBrRsfqsiy2faB3Q2cr5dqwBCy51VtxXVxBGoQ3RBTRV

Error: connect QmZBrRsfqsiy2faB3Q2cr5dqwBCy51VtxXVxBGoQ3RBTRV failure: dial attempt failed: 1 error occurred:
* <peer.ID QmGkd4KN> --> <peer.ID Qm3RBTRV> (/ip4/104.131.131.82/tcp/4001) dial attempt failed: dial tcp4 0.0.0.0:4001->104.131.131.82:4001: i/o timeout

#2

It looks like that node is refusing all new connections.
