Hello Team - I started using Nextcloud from the last couple of days. My initial setup was
Rasp 4, 2 TB data drive, 1 TB backup drive. The system was running smoothly, up until my last week when my data drive HDD crashed last week. Since my system was fairly new, and I had all my data in the backup, I thought I will do a fresh install.
Here are some more details -
| NextCloudPi version | v1.25.0 |
|---|---|
| NextCloudPi image | NextCloudPi_03-28-20 |
I reflashed the SD card, plugged into Rasp4, and added 1 TB SSD as a data drive. It worked for 10-15 mins and then the same error.
Nextcloud check error
My initial thought was it might be a faulty SSD or SATA to USB 3.0 cable. So I tried the same setup with a flash drive, and 2 other HDD, got the same error.
Also, when I set up my data into the USB drive through the wizard, I get this error. (USB/ HDD was formatted as BTRFS)

Error reading data directory. Is NextCloud running and configured?
I found a similar post ([NCP] Nextcloud check error), but it seems it was resolved by “latest kernel update”. I tried that too, no luck
