Hi @featheredtoast until I rebuilt yesterday, I had not manually rebuilt since following the changes suggested to app.yml mentioned in this thread above (August 2025) - though I had updated from whatever beta was current in August, to 3.6.0.beta3-latest via the Discourse UI a few days ago.
As a Linux illiterate, I can find no sign of acme.sh anywhere in my Digital Ocean droplet.
the /opt directory itself is empty other than containerd digitalocean
Thanks for that - I see a list of options with that command, but nothing that obviously relates to a dry run that might test whether renewal will occur. Not the end of the world.
