Cloud.reshaped.ch uses an invalid security certificate

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:

https://cloud.gut-haidehof.de/nextcloud

I ran this command:

sudo /usr/local/bin/certbot-auto --apache

It produced this output:

My web server is (include version):

Apache/2.4.25

The operating system my web server runs on is (include version):

debian 9

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’m using a control panel to manage my site (no, or provide the name and version of the control panel):

no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

certbot 0.35.1

Every time i try to connect to cloud.gut-haidehof.de I am being redirected to cloud.reshaped.ch.

I had setup lets encrypt certificates for cloud.reshaped.ch before but without any success.

now It says that my cloud.gut-haidehof.de certificate is not valid for cloud.reshaped.ch (of course).

how can I remove the redirection from gut-haidehof to reshaped?

I already specified the correct domain in my sites-available/* directory.

many thanks in advance!

Hi @benjmanable

there is a redirect defined ( https://check-your-website.server-daten.de/?q=cloud.gut-haidehof.de ):

Domainname Http-Status redirect Sec. G
http://cloud.gut-haidehof.de/
91.35.199.24 302 https://cloud.reshaped.ch/ 0.063 E
https://cloud.gut-haidehof.de/
91.35.199.24 302 https://cloud.reshaped.ch/ 0.967 A
https://cloud.reshaped.ch/ -1 2.530 R
NameResolutionFailure - The remote name could not be resolved: 'cloud.reshaped.ch'

http and https.

So first check your config

apachectl -S

to find your vHosts.

Then check these, where the redirect is defined. Perhaps you have a .htaccess.

Hi @benjmanable,

Welcome to the community forum!

I believe there are several issues going on here.

  1. DNS
$ dig cloud.gut-haidehof.de +short
91.35.199.24
$ dig cloud.reshaped.ch +short
<no output>
  1. Apache vhost configuration: can you show me the output of apache2ctl -S please?

@JuergenAuer beat me to it :stuck_out_tongue: :racing_car:

Apache vhost configuration: can you show me the output of apache2ctl -S please?

output is:

What's the content of both files?

There may be redirects defined.

default.conf:

<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	DocumentRoot /var/www
	
	#Redirect "/" "https://192.168.2.126/"
	Redirect "/" "https://cloud.gut-haidehof.de/"

	ErrorLog ${APACHE_LOG_DIR}/error.log

ServerName cloud.gut-haidehof.de
SSLCertificateFile /etc/letsencrypt/live/cloud.gut-haidehof.de/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/cloud.gut-haidehof.de/privkey.pem

</VirtualHost>
</IfModule>

In your port 443 vHost:

That's wrong, normally, that's a loop.

But it looks that this isn't your complete configuration.

Because ( https://check-your-website.server-daten.de/?q=cloud.gut-haidehof.de )

Domainname Http-Status redirect Sec. G
http://cloud.gut-haidehof.de/
91.35.199.24 302 https://cloud.reshaped.ch/ 0.110 E
https://cloud.gut-haidehof.de/
91.35.199.24 302 https://cloud.reshaped.ch/ 1.000 A
https://cloud.reshaped.ch/ -1 2.453 R
NameResolutionFailure - The remote name could not be resolved: 'cloud.reshaped.ch'

there is the wrong redirect again.

And your configuration is buggy, HSTS over http looks bad.

What says

apachectl configtest
apachectl fullstatus

apachectl configtest

says

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK

and

apachectl fullstatus

says

w3m: Can't load http://localhost:80/server-status.

there are still more files in the sites-available directory of apache:

nextcloud-ssl.conf

says

<VirtualHost *:443>
        ServerAdmin benjaminpreiss@protonmail.com
        DocumentRoot /var/www/nextcloud
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/apache2/ssl/nextcloud.crt
        SSLCertificateKeyFile /etc/apache2/ssl/nextcloud.key
</VirtualHost>

and

dietpi-nextcloud.conf

says

# Based on: https://docs.nextcloud.com/server/stable/admin_manual/installation/source_installation.html#apache-web-server-configuration

# Redirect OCM/OCS provider requests to Nextcloud endpoint:
Redirect permanent /ocm-provider /nextcloud/ocm-provider
Redirect permanent /ocs-provider /nextcloud/ocs-provider

<Directory /var/www/nextcloud/>
        Options +FollowSymlinks
        AllowOverride All

        <IfModule mod_dav.c>
                Dav off
        </IfModule>

        SetEnv HOME /var/www/nextcloud
        SetEnv HTTP_HOME /var/www/nextcloud

</Directory>

So,

removing the
Redirect "/" "https://cloud.gut-haidehof.de"
entries in all
available-sites
made it work.

also (because i am using nextcloud) I had to add a trusted domain entry
2 => 'cloud.gut-haidehof.de',
in nextclouds
config/config.php

thanks for the perfect help!
