My domain is: szzx.work

I ran this command:

certbot certonly \ --dns-cloudflare \ --dns-cloudflare-credentials ~/szzx.work.cf.ini \ -d *.szzx.com -v
It produced this output:

An unexpected error occurred:
ImportError: cannot import name 'constants'

It looks like you have multiple Certbot installations. This one was probably installed with pip and is taking precedence over the Certbot you installed with snap.

Try removing that pip-installed Certbot binary:

sudo rm /usr/local/bin/certbot
3

This is not the snap version of certbot. Did you remove all other versions of certbot besides the one from snap?

Is the typo only in this post or also in the configuration?
