Hi,  
I have upgraded Buster to Bullseye with a running dietpi system. The system has had a nextcloud service and a smb.  
SMB kept on working, however nextcloud did not. Tried many thing, read lots of forums and decided to uninstall NC and hava a fresh install. After download however i can not reach nextcloud by \<ip/nextcloud/\> and have a 503 service unavailable error.  
What did i do wrong?  
thanks

all services are running?

```nohighlight
dietpi-services status

```

Web server is reachable by it’s IP?

```nohighlight
http://<ip>

```

Did you restored a backup or is it an empty installation?

hmm there seems to be an issue with CalDAV. At least some errors generated by CalDAV/BirthdayService.php

```nohighlight
{"Exception":"Error","Message":"Trying to access array offset on value of type null at

```

And you are sure it was an empty installation? Nothing got imported during install?
