I have a scheduled backup job running every night, which exports my Panorama config to a backup server, it is running for over a year now without any problem.
Yesterday I went over the config, changed the time and permitted the config.
This morning I saw that the backup failed due to missing ECDSA SSH key.
Failed exporting config bundle via ssh to 1x.xx.xx.xx. No ECDSA host key is known for 1x.xx.xx.xx ...Host key verification failed...lost connection
The test connection button on the backup schedule page asks if I want to add the key, system says it added the key but it seems to do nothing. Same message when I press the button again, same error message when the backup job runs again.
Im on Panorama version 10.2.2
Has anyone a hint how to fix or work around that issue?
Did you try the suggestion from ahandoo? I had no luck with it.
Did the update to 10.2.2-h1 during weekend but still the same situation, seems to be a bug. Is there any way to report this issue officially to Palo Alto Networks?
Is it possible to create the scheduled backup via CLI?
Ideally, the device should update the ssh key in the known-hosts file after following the article. It is interesting to know that the CLI test work fine but the schedule for config export.
As it does not work, then the TAC may access the known-hosts file to check if there are any issue or if this is any Bug.
Have you tried reaching out to the TAC regarding this?
Same here, we checked the issue yesterday with our PA support partner and opened a case at PA. Hopefully it doesn't take that long to fix as the ACC IP issue...
In the meantime I'm using anonymous ftp together with a copy script which moves the backup file away, shi**y solution I know but better than nothing.
Keep you up2date
I have a TAC remote session today in the afternoon, I will let you know the result here. At the moment I have only the case number from my palo alto support partner but this is not the real PA case number. If they have no short workaround today and we have to way for a fix then I'll ask my partner to send me the PA case number and then I can give it to you.
