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. crt.sh | 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:
alakhras-sy.com
I ran this command:
sudo certbot --nginx -d alakhras-sy.com -d www.alakhras-sy.com
It produced this output:
The following errors were reported by the server:
