Certificate renewal fails

[hacmac11]

Hello,

I have nextcloudpi installed on my raspi (NC version 25.0.5.1, NCpi version 1.51.2).
Operating System: Debian GNU/Linux 11 (bullseye)
Trying to renew my letsencrypt certificate results in following error:

All renewals failed. The following certificates could not be renewed:
/etc/letsencrypt/live/xxxx.spdns.de/fullchain.pem (failure)

---

1 renew failure(s), 0 parse failure(s)

IMPORTANT NOTES:

• The following errors were reported by the server:Domain: xxx.spdns.de
  Type: connection
  Detail: xx.xx.xx.xx: Fetching
  https://xxx.spdns.de/.well-known/acme-challenge/xxxxxxxxxxxxxxxxxxxxxxxxxx:
  Error getting validation data

The entered domain name is correct. What steps do I have to perform to check my configuration?

Thank’s a lot!!
