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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Failed to renew certificate alkarkhi.com with error: The manual plugin is not working; there may be problems with your existing configuration. The error was: PluginError('An authentication script must be provided with --manual-auth-hook when using the manual plugin non-interactively.')
My web server is (include version): nginx v1.14.2
The operating system my web server runs on is (include version): Debian v10.10
Probably not. Have you been able to renew the cert before using certbot renew? Because the error message suggests you initially issued the cert using --manual. If you did that, you can't renew automatically, and if you think about it for a minute, the reason is obvious--when you use --manual, cert issuance requires manual intervention. If you're running non-interactively (as renew does), there's no way to provide that manual intervention.
I see the forwarding, but if the rest of the site is not serving the same content, then I can only assume they are either not on the same system or won't provide the same content once secure.
Recall that step one is having a fully functional web site.
This seems to fail that as is.
No but that doesn't negate the lack of synchronization of the rest of the site.
So that even if we "WIN". we will soon see another TOPIC with "Sometimes my site works and sometimes it doesn't after install LE cert."
[When it did that even before the cert was obtained]
