I have a problem with renew letsencrypt ssl.
3 Months ago, at the first time I created ssl for my domain forestlink.net successfully.
But now I failed to renew. I ran the command /usr/bin/letsencrypt renew
and it returned:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org

I don’t know why the script always checks https://forestlink.vn/.well-known/… instead of forestlink.net.
So, I can’t verify my domain anymore. I have checked my DNS settings on Cpanel, I’m sure there is nothing for forestlink.vn.
Please help me.
Thank you all in advance!
