Before Virtualmin got direct support for letsencrypt certificates generation I used letsencrypt-auto script from well known letsencrypt git repository.
After virtualmin got tools for generating certificates using letsencrypt, all my attempts to generate certificates using these tools ended up with strange error without any useful error message:
Requesting a certificate for .... from Let's Encrypt ..
.. request failed :
If you have the same trouble, just remove all letsencrypt scripts following list of locations where letsencrypt has its components: https://community.letsencrypt.org/t/how-can-i-completely-reinstall-lets-encrypt-delete-all-old-certificates-and-start-fresh/10689/4.
After I removed all mentioned directories, virtualmin's letsencrypt tools started working like a charm!
Thank you guys from virtualmin and letsencrypt for your great job!
