Plugin Not Compatible with Certbot = 5.1.0

[L0ric0]

Thank you for developing the plugin.

Currently the plugin does not work when running certbot 5.1.0. I suspect that it also does not work with >= 5.0.0 but I am unable to test this, as I'm using my distros certbot package and the distro does not support partial upgrades.

The content of the certbot log with the error is attached below.
Thank you again for the plugin.

certbot.log:

Thanks for your report.

In the environment (potentially a venv) where you run certbot, can you check whether dnspython is installed?

You should be able to check using pip list.
