How to manage OpenBalena Certificate expiration

Hello,
we are hosting an OpenBalena Server and we are planning to deploy a lot of devices under it.
We have installed certificates as in the guide and everything is running fine by now, but we have some conerns about what happen when the certificates expires.
OpenBalena gives a self-signed certificate, as far as I know it is a 10 years CA certificate and 2 years client certificate.
What happens after 2 years?
Do we need to perform some actions on each individual device?
It will be a lot of them… so we have to have a clear plan of action.
Does the certificates have some auto-renewal or is there a way to massively update the certificates via API?

Thank you,
Max

I’m making some integration on the previous request.
We tried to set the Production certificate using letsencrypt using the quickstart -c option.
At first we got some errors, but we managed to overcome them thanks to this post:

Commenting the lines 182:183 on cert-provider.sh AND update the Dockerfile to use version 3.0.1 of ACME script “seems” to have solved the installation.
Now the log actually say it has installed a PRODUCTION certificate.

But actually when we test the api.mydomain.com we still don’t have a trusted certificate.
The issuer appear to be (STAGING) Artificial Apricot R3

Why it isn’t a PRODUCTION certificate?
Could we use a self-signed certificate that expires in 100 years?
It’s important to us not to interrupt workload and communications for a certificate expiration, and we will have a lot of devices.

Here is the log from the cert-providers container:

UPDATE:
I still cannot find a solution.
I’ve done

docker system prune -a
docker volume prune
quickstart -U {email} -P {password} -c -d {domain}

But no luck so far…

I’ve connected to cert-provider container and made some tests with the file cert-provider.sh
STAGING certificate does install, but doesn’t verify, so the operation is aborted.
Commenting lines 182:183 as suggested in the other topic skips to the PRODUCTION certificate, but it gives this error:
cat: can't open '/usr/src/app/certs/{domain}/{domain}.cer': No such file or directory

That’s the reason we cannot get a PRODUCTION certificate I guess…
Can someone point me to the right direction?
