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](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. SUBDOMAINS entered, processing Only subdomains, no URL in cert Sub-domains processed are: -d kiwix.lucadent.ro -d nextcloud.lucadent.ro -d pass.lucadent.ro -d server.lucadent.ro E-mail address entered: office@lucadent.ro http validation is selected Generating new certificate Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator standalone, Installer None Obtaining a new certificate Performing the following challenges: http-01 challenge for kiwix.lucadent.ro http-01 challenge for nextcloud.lucadent.ro http-01 challenge for pass.lucadent.ro http-01 challenge for server.lucadent.ro Waiting for verification… Challenge failed for domain kiwix.lucadent.ro Challenge failed for domain nextcloud.lucadent.ro Challenge failed for domain pass.lucadent.ro Challenge failed for domain server.lucadent.ro http-01 challenge for kiwix.lucadent.ro http-01 challenge for nextcloud.lucadent.ro http-01 challenge for pass.lucadent.ro http-01 challenge for server.lucadent.ro Cleaning up challenges Some challenges have failed.

The combination of this: > [@Eugenia20259478](#): > > Authenticator standalone and this: > [@Eugenia20259478](#): > > [90.95.143.143]: “\r\n404 Not > Found\r\n\r\n makes me suspect that the machine on which you're running certbot is not the machine that those domain names resolve to. Is it? Because if not, there's your problem. ---

Can you run the Let’s Encrypt client application on the same machine where the certificates will ultimately be used? ---

Sorry, I didn’t quite understand your answer to my question. Could you also run a Let’s Encrypt client application on the same server where the subdomains are pointed, instead of only running it on the server that they’re not pointed to? ---

Hello Schoen. Thank you for helping me… I have a personal server at home where i run let’s encrypt, nextcloud, bitwarden…and i have a domain at a local provider, there i keep my office website. On my domain i have made 3 subsdomains, enter them on my home server let’s encrypt (that is an Unraid System - debian /ubuntu base), i run it on a docker container. when i try to validate everything,i get that error. all i want do is to access my bitwarden and nextcloud outside my local network… for that i try use let’s encrypt and duckdns ---

Is it possible that the Docker container doesn’t have the relevant permissions to create publicly visible files for the domain control challenges? ---
