Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:/mbox.toulouse-les-orgues.org
I ran this command: sudo certbot --nginx certonly -n -d mbox.toulouse-les-orgues.org
It produced this output:
Cert not due for renewal, but simulating renewal for dry run
Plugins selected: Authenticator webroot, Installer None
Attempting to renew cert (mbox.toulouse-les-orgues.org) from /etc/letsencrypt/renewal/mbox.toulouse-les-orgues.org.conf produced an unexpected error: Deserialization error: Expecting value: line 1 column 1 (char 0). Skipping.
All renewal attempts failed. The following certs could not be renewed:
My web server is (include version): ubuntu 18.04
The operating system my web server runs on is (include version):iredmail latest
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):no
