I'm not able to connect with fleet server due to
Failed enrollment request to <> (Request error: certificate verify failed) retrying
. I'm following FAQs to make sure I don't miss anything. Here is what i get when I curl the enroll endpoint.
Copy code
❯ curl -v -X POST <>
*   Trying
* Connected to <|> ( port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* successfully set certificate verify locations:
*   CAfile: /etc/ssl/cert.pem
  CApath: none
* TLSv1.2 (OUT), TLS handshake, Client hello (1):
* TLSv1.2 (IN), TLS handshake, Server hello (2):
* TLSv1.2 (IN), TLS handshake, Certificate (11):
* TLSv1.2 (OUT), TLS alert, unknown CA (560):
* SSL certificate problem: self signed certificate
* Closing connection 0
curl: (60) SSL certificate problem: self signed certificate
More details here: <>

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
I'm not sure if i understand the significance of
* successfully set certificate verify locations:
* CAfile: /etc/ssl/cert.pem
CApath: none

If it’s self-signed as indicated by your curl output, you need to specify the
flag. See

Ahh, yes. It is self signed and I have already specified the
path in
(The pem file downloaded form fleet web UI). I also cross checked that the fleet FQDN matches the CN in the
file. But I still can't enroll my client on fleet server. One thing I noticed is that openssl appends the
to the FQDN so the final CN in the certificate is
I hope that has nothing to do with the certificate failing to verify?

Probably unrelated, but finally got around to looking at my test environment and i had the Sectigo Cross-signed CA issue... Had to update all client certs...
Secondly, some CA give the pem in a reverse order, and had to reverse in notepad the order to make work

@koba did you have any luck in getting your issue fixed?
NM got this working I used tls--server--certs and the .pem

Sorry I saw this and thought I replied but apparently I didn't. Yes I was able to fix it. I was generating certs with "https" included in the CN value. I dropped the https prefix and it worked. I'm not sure if this is right behavior though. Perhaps the error could be a little more clear? @zwass
