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: bfinationalarchivemedia.bfi.org.uk
I ran this command: sudo certbot --nginx -d bfinationalarchivemedia.bfi.org.uk -d www.bfinationalarchivemedia.bfi.org.uk
It produced this output:
Traceback (most recent call last):
