Error: Failed to send transaction successfully to the orderer status:SERVICE_UNAVAILABLE

cause :

if there is no leader orderer available(in case of crash fault) or your orderering service is down in those cases we   receive SERVICE_UNAVAILABLE at client end.

solution :

make sure your orderering service is running and there are enough orderer node to maintain the quorum.

if there are n number of faulty orderering node:

in kafka orderering service 3n + 1 orderering node would be require to maintain the quorum.
in raft orderering service 2n + 1 would be required
