Truenas core certificate expiring

Hi All,

Product/Version: TrueNAS-13.0-U6.2
HostName: truenas.local (Home user/no domain)

I searched this excellent forum, and found a topic that I cant find anything on…
I hope you can please help me here…

My Truenas Core gives the following:
NOTICE: " Certificate ‘freenas_default’ is expiring within 4 days."
as far as I googled around, it seems like I should create a new certificate?

I found this post: How to renew TrueNAS certificate? | TrueNAS Community

  1. System → CAs → Add, type defaults to Internal CA
  2. System → Certificates → Add, set the Type to Internal Certificate
  3. You can now select that new cert for whatever you had been using the default cert for, then delete the default cert.

However this leaves a bit of unanswered questions for 1&2, what should I select with the goal of replacing the default certificate?
How do I change from the default to the created?
If it expires, what will the impact be?

Kind regards,
Lefa

You can create the new CA then head over to System then General to swap out to the that new CA. Since you are already using self signed cert I think the browser will just keep giving the same error.

Thank you for fast response Tom.

It is actually not the browser, it pops up as an alert under the bell.
Is it only the browser it would affect? Or does it for example affect replications?
I’ll guess you would have mentioned it if that was the case, but just top make sure?

I can also see that my backup nas have a certificate with a valid period of 1 year, like this machine.

Hello everyone:
First you need to create a CA and then a Certificate.
Second go to System → General.
Then in the first line select your new certificate.
And then save.

error_cert
I don’t remember if need to reboot the system.

Sorry for my english is not my native language.

I hope this can help you.
Regards.

The replications are done via the SSH keys, not the CA key.

Thank you for the clarification.
