Hallo,
ich wollte gerade die Lets Encrypt - Zertifikate für meine Internetseite (http://www.topsaaten.de) aktualisieren (sudo certbot renew). Jetzt bekomme ich folgende Fehlermeldung:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Processing /etc/letsencrypt/renewal/www.topsaaten.de.conf

Cert is due for renewal, auto-renewing...
Plugins selected: Authenticator standalone, Installer None
Attempting to renew cert (http://www.topsaaten.de) from /etc/letsencrypt/renewal/www.topsaaten.de.conf produced an unexpected error: HTTPSConnectionPool(host='acme-v02.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fcfb9cbd040>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')). Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/www.topsaaten.de/fullchain.pem (failure)
Woran liegt das? Und vor allem, was kann ich dagegen tun?
Danke!
