Letsencrypt not renewing domain shared between users

[alx359]

Thanks, eris.

Couldn’t find anything meaningful in the logs, so tried to regenerate the cert manually, but got a validation status 400 error. Googling for it gave me this useful piece of advice that worked, for now:

Let's Encrypt validation status 400. Details: Unable to update challenge :: authorization must be pending

Maybe you have another web alias on the domain, besides the default www ? If you have another alias (e.g. super.mydomain.com) then you need to have an A record “super” to point to the server’s IP (like the www one). If you have more aliases, then you need an A record for each one of them.

Will see how it goes after 3 months.
