Server error : No ECDSA host key is known for netadmin2.intra.chu-rennes.fr . Host key verification failed.

Hello team,

I have a problem with my export configuration Panorama via  scheduled task.

When I make a test SCP server connexion I have this mesage : 

Before upgrade to 10.2 the export was working fine.

I have also saw that PAN-188052 talk about this issue. Do you know how to fix it ? 

Could you help me please tu understand this problem.

Thank you in advance.

Hi, I have the same trouble in 10.2.2-h2 ... Do you fix it?

Actually spent a few hours with TAC last night, bottom line, their is a work around, where they log into to root and delete the host/key folder and then you can try again to import the key through the article

https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA14u000000HByDCAW

This this not work for me, and they are researching a possible workaround, if there is any.

They said it is a know issue and it is said to be fixed in 10.2.4.  we are running 10.2.3 and .4 is not available for download.

It seems the key the gui is looking for is the md5 "hex key word" but what you import is actually a alaphnumberic equivelant.

ive tried all kinds of combinations but have not gotten anywhere.

Thanks everyone for posting about this. Ran into the issue also immediately after upgrading Panorama to 10.2.3H2. This saves me a ticket since it appears there is no current fix.

[miguelMA]

unfortunately no, but they should be able to log into root and do the needful, like they did in my case.

I had this issue under the same circumstances and TAC were also able to resolve it by logging in as root and manually removing the old key, so it may be worth asking them to try for you.

The known issue id is PAN-194805. Probably fixed in March 10.2.4 release. A mentioned, in the meantime, you can contact support and have them login to root.

Seem also still be an issue  in 10.2.3-h4,   but i also don't see the bug id back in the know issue list.

Does anyone know under which bug id this will be fixed and also in which release?

Thanks!

[djr]

We hit this issue again after having it fixed, but following the H4 patch installation.  We are still working on the understanding that hit will be resolved in 10.2.4

Hello,

After an upgrade to 10.2.4 the issue appear again. I will contact the TAC to connect as a root like the first time I had this issue.

Hi,

Confirm. However the test option works well and sample file creates. While doing scheduled task there is an error only in log file :

admin@Panorama> less mp-log logd.log

Same issue on PA-850 after upgrade from 9.1.4 >10.2.0>10.2.4 .

Support me ask to roll back and follow the recommended upgrade path

this error needs root access to be fixed

For our Panorama the upgrade from 10.2.3-h2 to 10.2.4 did not fix the scp issue. The test option works but I did not asked for that, I just want a working scheduled scp. This means I need to contact TAC again to fix it as root for us.
