Certificate renewal error

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: vusnet.co.bw

I ran this command:sudo certbot certonly -a manual -d vusnet.co.bw --preferred-challenges http

It produced this output:
certbot.errors.PluginError: An authentication script must be provided with --manual-auth-hook when using the manual plugin non-interactively.2026-04-21 10:02:24,571:DEBUG:certbot._internal.plugins.selection:No candidate plugin

As the message notes, that is not the correct syntax for using a manual method.

And, you have an Apache server replying to HTTP and HTTPS requests so you would not normally use any "manual" method.

I can see from the public cert logs you got a cert in January that recently expired. You also say you are using cPanel. Did you also use Certbot to get that cert in Jan? If not, please explain how you got that cert.
