Remote backups - Could not authenticate

Hi
I am trying to get remote backups working from my nagiosxi server to a backup nagiosxi server both are centos 7 vms.
When i try an authenticate using ssh keys i get Could not authenticate. However if i use a password it works. i can not see anything in /var/logs/secure on the backup server to give any clues to why it is failing
I have looked at this post
https://support.nagios.com/forum/viewto ... 47&start=0 but that has not helped.
Any ideas ?

I'm not sure that SSL errors will be written there. Can you try looking in the following logs instead?
Code: Select all
/usr/local/nagiosxi/var/components/scheduledbackups.log
/usr/local/nagiosxi/var/cmdsubsys.log
/var/log/httpd/error_log
/var/log/httpd/access_log
That may give you a more detailed picture of what is going on.
Could the SSL certificate be expired?
It never hurts to send ( PM ) us a profile either! We can find lots of information about your system in there. You can download the profile by navigating to
System Profile under
System Config on the left pane > and clicking the
Download Profile button on that page.

Can you go to
Admin > System Backup > Scheduled Backups > SSH tab and show a screenshot of that page?
Did you copy the public key from the Nagios XI server to the authorized_keys on the remote "backup" server?
Example:
Code: Select all
ssh-copy-id -i /usr/local/nagiosxi/var/keys/ssh.xi.xxx.pub user@remoteip
Try testing the connection from the command line by running:
Code: Select all
sudo -u nagios ssh -i /usr/local/nagiosxi/var/keys/ssh.xi.xxx user@remoteip
enter the private key password when asked (you can view/copy it from the GUI) to see if the connection will succeed.
Example:
Code: Select all
[root@main-nagios-xi]# sudo -u nagios ssh -i /usr/local/nagiosxi/var/keys/ssh.xi.1594741274 [email protected]
Enter passphrase for key '/usr/local/nagiosxi/var/keys/ssh.xi.1594741274':
