Ah thanks for the confirmation and the reports - Nat was able to triage this and found there was a quote in the script that needed escaping. Let us know if the next renewal goes better.

Do we need to update or rebuild ?

Yes, a rebuild will be necessary to inherit the new configuration for this

So, over the next three months, we can expect a rash of self-hosters seeing failed certificate renewal, if they last updated before this bug was introduced and haven’t yet updated since yesterday’s fix?
Can I suggest this is highlighted in the next regular release?
(For myself, my certs expire late Jan, and my installations, updated to the 2025-12-latest in late Nov, do have the bug.)

I think it’s still true that if you rebuild you get a new cert and it’s unlikely that we’ll go three months without an update that requires a rebuild. But if you’re someone who doesn’t do command line upgrades then you’ll likely get a cert error. This bug has been around in various ways for most of this year.
