The client lacks sufficient authorization :: Invalid response

Hi

I installed Apache today and ran sudo certbot --apache -d… after I already had certbot working for -standalone. With that I ran into some problems like a new certificate folder “/etc/letsencrypt/live/epikur.duckdns.org-0001” (and then 0002 on the next try after deleting 0001). I “solved” the problem by purging apache and certbot and re-installing them. As far as I can tell the next attempt with sudo certbot --apache -d… was successul, but the renew dryrun immediately afterwards produced the following error:

My domain is: epikur.duckdns.org

I ran this command: sudo certbot renew --dry-run

It produced this output:
Processing /etc/letsencrypt/renewal/epikur.duckdns.org.conf

IMPORTANT NOTES:

My web server is (include version): Apache/2.4.29 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu Server 18.04 (with Mate Desktop)

My hosting provider, if applicable, is: -

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I went through the suggested similar topics but haven’t found a solution yet (e.g. placing an OK file in acme-challenge to see if that works; it does). I hope someone has an idea?

Can you please check if all the above domain get a corresponding virtual host in your Apache configuration? (Instead of a default virtual host with unknow names?)

Thank you

Thank you for the reply, but I’m not sure I understand, sorry. But if I do, I added the second domain as an alias:

epikur.duckdns.org.conf
<VirtualHost *:80>

    ServerAdmin admin@epikur

    ServerName epikur.duckdns.org

    ServerAlias vipa.duckdns.org

    DocumentRoot /var/www/epikur.duckdns.org/html

    ErrorLog ${APACHE_LOG_DIR}/error.log

    CustomLog ${APACHE_LOG_DIR}/access.log combined

RewriteEngine on
RewriteCond %{SERVER_NAME} =epikur.duckdns.org [OR]
RewriteCond %{SERVER_NAME} =vipa.duckdns.org
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

Well I did a complete purge again and now it works, I will never know what happened, but at least it works.
