Could not load host key: /etc/ssh/ssh_host_ecdsa_key

As an AI language model, I don't have access to your server or computer's configuration files. However, in general, this error message indicates that the ssh daemon (sshd) is unable to load the host key for the ECDSA algorithm. This could be due to the key file being missing or inaccessible, or the file permissions not being set correctly.

To resolve this issue, you can try the following steps:

1. Check if the key file exists at the specified location (/etc/ssh/ssh_host_ecdsa_key). If it does not exist, you can generate a new key file using the ssh-keygen command:

sudo ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key

2. Ensure that the file permissions for the key file are set correctly. The file should be owned by the root user and have read-only permissions for the owner:

sudo chown root:root /etc/ssh/ssh_host_ecdsa_key
sudo chmod 400 /etc/ssh/ssh_host_ecdsa_key

3. Restart the sshd service to apply the changes:

sudo service sshd restart

If the issue persists, you may need to check the sshd configuration file (/etc/ssh/sshd_config) to ensure that the correct key file path is specified for the ECDSAHostKey directive.
