I have verified that my dns has the correct A record and that the ports are forwarded correctly.

I found this issue and tried exec'ing into the container to install that package but I still receive the error.

Any help would be appreciated, thanks :)

Which DNS provider are you trying to use ?

[richardklint]

Right now I'm using 1.1.1.1 and 1.0.0.1, should I try Google's?

[jlesage]

Sorry I was talking about the certificate generation: are you enabling Use a DNS challenge ? If yes, are which one are you using ?

[richardklint]

No, I'm not using one.

[jlesage]

Are you using the latest version of the image ? There was an issue with certbot that has been fixed.

[richardklint]

Yes, I'm on the latest, v1.17.0

[richardklint]

@jlesage Fixed it by exec'ing into the container and running pip install future and that fixed it. Would recommend updating the Dockerfile to include that.

pip install future fixes the issue for me as well
