Auto Renewal does not work. Where to start looking?

[Salvora]

Hello,
I just found this and set it up a couple of months ago thinking everything was going to go smoothly but apparently a small problem occurred. Auto renewal is not working for me. 10 days until certs expire.
I tested it with a manual renew on the dashboard and it worked fine.
I restarted the function app on Azure. Still no renewal
Then I checked the tags of the certificates after reading some older discussions. They were properly tagged with issuer Acmebot and endpoint.
Then I checked "RenewCertificates_Timer" Invocations of the function app.
this was also fine

Then looked other discussion posts and issues but could not find anything similar to my case.
So I am stuck. Any helping hand here?

Please check the execution log for RenewCertificates_Orchestrator. If the target was not found, the following log should be output.

yep, as you have said, the certs were not found but why?

These certs were issued directly from the keyvault-acmebot. I did not modify anything or import certs from outside.

I don't know the cause yet, but since automatic updates were executed a few days ago in my environment, I think it may be an issue specific to the environment.

Only the certificates displayed in the Managed certificates section of the dashboard are eligible for automatic renewal, so please check that they are displayed there.

There is a property called Acmebot:RenewBeforeExpiry that affects automatic updates, but is that value set in the Function App?

Yep, thanks for clearing this up. This was the problem. Now, fixed.
