letsencrypt.cli:Exiting abnormally

I tried installing a letsencrypt cert through the latest version of the freedombox, it fails with this log. I can't find the reason for failure in the message, thanks for any help!

Does this help?

Haven't heard back on this, so I'm closing this issue.

Sorry for not replying, this was due to wrong usage of let's encrypt in the freedombox package. I think it had to do something with how the message box was used, but should have not been used, not fully sure... But it has been fixed within the freedombox package shortly after I reported and was no bug in let's encrypt at all.
Thanks!
