My ipfs node can't connect to other peers, i have the latest go-ipfs 0.8.0 and ipfs desktop 0.15.0, peers count is zero.
My ipfs node have zero peers connected, when i am connected to my home network 0 peers and with cellular data to my computer the node works fine.
I believe you've been bitten by go-ipfs#8120.
Currently the solution is simply to do these steps to get peering rolling again. In IPFS Desktop:
/ip4/149.56.89.144/tcp/4001/p2p/12D3KooWDiybBBYDvEEJQmNEp1yJeTgVr6mMgxqDrm9Gi8AKeNww
That will add a peer to the peer table and allow the IPFS daemon to start properly with a swarm of peer connections.
