hi, michalvasko, could you help to check my problem:

netopeer2-serve:

[2023/07/05 23:47:11.559385, 1] ssh_packet_server_curve25519_init: Could not sign the session id [ERR]: LN: SSH key exchange error (Could not sign the session id).

netopeer-cli:

listen Waiting 60s for an SSH Call Home connection on port 4334... nc ERROR: Starting the SSH session failed (Received SSH_MSG_DISCONNECT: 11:Bye Bye). cmd_listen: Receiving SSH Call Home on port 4334 as user "root" failed.

Question: Does it depend on the OPENSSH which not yet installed in the ARM platform? And please give me some advice , thank you！

I have never seen the error so I will not be able to help. But it is an SSH problem so try updating the installed libssh, you mentioning ARM increases the chances you are using some old/faulty version of it.
