LE renew failed

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:pekatrack.de

I ran this command: PLESK: Press Let"s Encrypt renew button

It produced this output: Fehler: SSL/TLS-Zertifikat von Let’s Encrypt konnte nicht für pekatrack.de ausgestellt werden.

Das Token für die Autorisierung kann nicht unter http://pekatrack.de/.well-known/acme-challenge/RjSDqKms3aQAdyjAcjG-rvvpPrKGdnjUGLjnVDHpyBI aufgerufen werden.
Um das Problem zu beheben, machen Sie die Tokendatei unter dieser URL verfügbar.

Hi @Peka

The server is always

Server: Jetty(9.4.14.v20181114)
X-Powered-By: PleskLin
MS-Author-Via: DAV

Looks the Plesk doesn't find the correct webroot of that server.

But: Plesk is a "closed world". Is there an option to define the webroot explicit?

Find your webroot, then create the two subdirectories


there a file (file name 1234), then try to load that file via


Or use my online tool with pekatrack.de/.well-known/acme-challenge/1234 to check ipv4 and ipv6, if that file exists.

Answer should be http status 200, not 404.

Dear Juergen, thanks for your help.
Now a file 1234 exist in http://pekatrack.de/.well-known/acme-challenge/
but could not found and get 404

Dear Juergen!
I found a problem with IPv6 configuration in the Apache configuration. The “call” was made to a wrong (or old) IPv6 adress i found in the Plesk Apache" protocol. First i like to update the IPv6 but I do not know how to update and where Apache will stored the wrong IPv6. So my last idea to be sure that i am on a good way, i disable IPv6 on my Strato VServer and run LE renew again. And it works. :slight_smile:
Now i must find out what to do if i enable IPv6 support again.
This is the result of a unknown user with the knowledge of a beginner.
Thanks again for your help!
