Hello,

What is your certbot version? It seems like as of Certbot 0.33.0 which was released a couple of months ago and according to the official documentation, --standalone-supported-challenges had been deprecated for a long time and does the same thing as --preferred-challenges.

I’ll ask for the tutorial to be updated.

Let me know if this was the case.
Regards,
Bobby

Thank you for the quick answer.
I asked a friend for help since this was above my pay grade.
He used the command
certbot certonly –preferred-challenges http -d mydomain.com and it worked.
He says an update to the doc would be good.
He also says that since there was already installed a listener on port 80,
the –standalone option was not required. This could be specified in the doc also.
