MPI_HYDRA_BOOTSTRAP issue is still existed.

[mpi_new_user]

The version that I used :

Intel(R) MPI Library for Linux* OS, Version 2021.1 Build 20201112 (id: b9c9d2fc5)
Copyright 2003-2020, Intel Corporation.

I want to launch my application by the command :

mpirun -hosts master,node1 -np 8 IMB-MPI1 Reduce 

After I finish the cluster environment setup (including the password-less login for ssh setting ,the hostfile about the name of nodes,the /etc/hosts...) ,I still meet this issue. The error message is below:

[mpiexec@master] check_exit_codes (../../../../../src/pm/i_hydra/libhydra/demux/hydra_demux_poll.c:117): unable to run bstrap_proxy on node1 (pid 345635, exit code 768)
[mpiexec@master] poll_for_event (../../../../../src/pm/i_hydra/libhydra/demux/hydra_demux_poll.c:159): check exit codes error

[mpiexec@master] main (../../../../../src/pm/i_hydra/mpiexec/mpiexec.c:1955): error setting up the boostrap proxies

Let me know if I'm missing something.

Thanks.
