udaddy test failure; RDMA_CM_EVENT_UNREACHABLE, error: 2

Trying to test UDP with AF_IB family using udaddy binary. However client is failing with RDMA_CM_EVENT_UNREACHABLE error. Here is the output

Using ConnectX-3 for IB support,

On Server,

./udaddy -b fe80::a0:9800:30:76f4 -f gid -P udp

rdma_bind_addr:848
udaddy: starting server
ucma_getaddrinfo: ret=0
rdma_bind_addr:848
rdma_listen:1543
rdma_get_cm_event:2089

On Client,
./udaddy -s fe80::a0:9800:30:76f4 -f gid -P udp

rdma_bind_addr:848
udaddy: starting client
ucma_getaddrinfo: ret=0
udaddy: connecting
rdma_resolve_addr:929 rdma_get_cm_event:2089 rdma_resolve_route:991 rdma_get_cm_event:2089
rdma_create_qp:1415
rdma_create_qp_ex:1351
rdma_connect:1495
rdma_get_cm_event:2089
udaddy: event: RDMA_CM_EVENT_UNREACHABLE, error: 2 test complete
rdma_destroy_qp:1426
return status 2

Running ucmatose with the following works fine,

On Server
./ucmatose -b fe80::a0:9800:30:76f4 -f gid -P ib

On Client
./ucmatose -s fe80::a0:9800:30:76f4 -f gid -P ib

Any suggestions on what I am missing/doing wrong,
