Unable to clean up challenge directory /var/www/kreator.ch/.well-known/acme-challenge
That probably just means the folder isnāt empty - not a real concern
Did it say āCongratulations!..ā ?
Unfortunately: non.
Seems to be a mix between certbot & certbot-auto.
Maybe I should uninstall the latter.
In the past I did not have these .Well-known/acme ā¦ (seems to me)
The answer was:
Domain: kreator.ch
Type: connection
Detail: Fetching

To 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 youāre using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
Rem: I do not have fire-wall
certbot-auto is a āself-containedā system.
It should not be causing a grief.
Well that is the same http problem we have been trying to overcome.
You need to do the opposite here then.
And force https authentication:
./certbot [whatever you had +] --preferred_challenges https
Do you have TeanViewer ?
I could give you access to my server this way. It would go faster ā¦
My āTVā PC(laptop) is down at the momentā¦
The fan wonāt spin so it refuses to boot [better safe than sorry I suppose].
So, no I canāt - sorry.
Lol.
root@vserv2200.swisslink.ch:/root# certbot renew --preferred-challenges https
An unexpected error occurred:
ArgumentTypeError: Unrecognized challenges: https
Please see the logfile 'certbot.log' for more details.
OMG!!!
cerbot --version
BRAIN FAAART!
Itās NOT HTTPS
use
TLS-SNI-01
certbot renew --preferred-challenges tls-sni-01
Certbot seems to be dead !!!
cerbot --version
-su: cerbot: command not found
cerTbot --version
[all lowercase]
It was all lowercase
c e r b o t
c e r t b o t
yours was missing the middle T
Sorry
certbot 0.10.2
but try this 
certbot renew --preferred-challenges tls-sni-01
No renewals were attempted.
Itsā very lateā¦
Itsā very earlyā¦
Itsā both.
Ok a step in the right direction.
certbot certificates
is empty, so it can't RENEW anything.
So you need to get new with "certonly" and without "renew"
And if it doesn't prompt you for domain(s), we'll have to add them with "-d"
[and possibly "--apache" also - or "--webroot"]
