@Ornias1993 Did you get it sorted out?

As I didn’t get any support from you on this issue, I stopped using this extention completely.

Hi marcelklehr, I had the same issue. In order to fix it, try not using your Nextcloud password. Instead, create a new app password:

1. In your Nextcloud account, please go to Settings -> Personal -> Security -> Devices & sessions
2. Enter any “App name”, e.g. “Floccus on Ubuntu”
3. Copy the password and use it in Floccus

Hopefully, it will help. Cheers.
