I used to use let’s Encrypt, and it work well. A few weeks ago I move my project to aws, but deleted all the let’s encrypt certificate I own by mistake. I also added my domain unicooo.com to HSTS which force people only can access my domain from https.
So now I can’t visit my site by http or https now ( because it force to https but my certificate is miss) as well as let’s encrypt can’t download the file for validate now, Any ideas?
python acme_tiny.py --account-key ./account.key --csr ./domain.csr --acme-dir ~/www/challenges/ > ./signed.crt
