Deploy agent 12.1.0.4 on AIX Server failing with: Algorithm negotiation fail.

We are trying deploy agent 12.1.0.4 on AIX Server and having the issue: Connection to the SSH daemon (sshd) on the target host failed with the following error: “Algorithm negotiation fail”. Ensure that SSH daemon (sshd) on the target host is able to respond to login requests.

We don´t have oracle password, so the connection is made by putting in named global credential public and private keys. The keys are DSA type.

In the sshd_config whe have:

PubkeyAcceptedKeyTypes YES

.ssh/authorizeskeys yes

Any ideas, please?

Thanks
