Ops and Admin

  • Am trying to connect to a replica set but am experiencing connection failures.
Socket closed [SSH Tunnel errors: (SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed,(SSH) Channel open failure: open failed
  • Am able to connect to each individual instance in the replica set.
  • Also rs.conf() does show all the members.

What else can I do?
