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: trebuen.selfhost.eu
I ran this command:
sudo certbot certonly --standalone --preferred-challenges http-01 -d trebuen.selfhost.eu
It produced this output:
WARNING: The standalone specific supported challenges flag is deprecated.
Please use the --preferred-challenges flag instead.

The following errors were reported by the server:

Error getting validation dataTo fix these errors, please make sure that your domain name was
entered correctly and the DNS A record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided. -
Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
My web server is (include version): mosquitto version 1.4.0, build 2019-02-13, no web server
The operating system my web server runs on is (include version):
Linux raspberrypi 4.14.98-v7+ #1200 SMP Tue Feb 12 20:27:48 GMT 2019 armv7l GNU/Linux
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 0.10.2
I want to use and run mosquitto in Principe according to that tutorial:
Running a selfsigned certificate inside my subnet works. I would liek to have the raspi reside behind the router (Fritz.box 7490) using port forwarding for port 8883. Unecrypted usage works properly on 1883. I can ping my domain address (trebuen.selfhost.eu) fom the raspi without problems.
What little piece is missing to get it running?
Best regards
Roland
