Verification via redirect

Server
#1

LS,

certbot renew failed with ‘timeout on verification’ error. This happened while Apache24 was configured:
[…]
<VirtualHost :80>
ServerName camelopardus.nl
ServerAlias www.camelopardus.nl*
Redirect permanent / https://www.camelopardus.nl/*
*
[…]
<VirtualHost :443>
ServerName camelopardus.nl
ServerAlias www.camelopardus.nl
SSLEngine On
DocumentRoot /usr/local/www/drupal7
<Directory /usr/local/www/drupal7>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Require all granted

Alias /.well-known/acme-challenge /usr/local/www/acme/.well-known/acme-challenge
<Directory /usr/local/www/acme/.well-known/acme-challenge>
Options None
AllowOverride None
Require all granted
Order allow,deny
Allow from all


When I took out the redirect:
<VirtualHost :80>
ServerName camelopardus.nl
ServerAlias www.camelopardus.nl
Alias /.well-known/acme-challenge /usr/local/www/acme/.well-known/acme-challenge*
<Directory /usr/local/www/acme/.well-known/acme-challenge>*
Options None*
AllowOverride None*
Require all granted*
Order allow,deny*
Allow from all*
*
#Redirect permanent / https://www.camelopardus.nl/*
*

It worked like a charm

It seems like redirect is not working, but:

“Our implementation of the HTTP-01 challenge follows redirects, up to 10 redirects deep. It only accepts redirects to “http:” or “https:”, and only to ports 80 or 443.”

What am I missing?

Hi @jbril

your redirect is wrong. Only "/" is redirected.

Use something like

RewriteEngine on
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

so all requests are redirected.

LS,

If the redirect is wrong, why does it (seem to?) work:

Perhaps you have additional definitions.

But checking your domain there is another error

You have ipv4 and ipv6 ( https://check-your-website.server-daten.de/?q=camelopardus.nl ):

Host T IP-Address is auth. ∑ Queries ∑ Timeout
camelopardus.nl A 83.161.65.240 yes 1 0

www.camelopardus.nl A 83.161.65.240 yes 1 0
AAAA 2001:981:4cee:20::bebe yes

But your ipv6 doesn’t work:

That’s critical, because Letsencrypt prefers ipv6.

But there is already a new Letsencrypt certificate.
