I previously set up DAVx5 (aka DAVdroid) on my Android smartphone to sync calendars and contacts with Disroot. This worked fine for a while until a week ago, when syncs failed with DAVx5 connection errors that show up on my phone's notification pane.
I tried to completely remove my Disroot account from my phone (which also erased any existing contacts and calendars on the phone) and re-add the account from scratch. Unfortunately, when I tried to add a new account (using the "Login with URL and user name" option), it gives me an error saying "Couldn't find CalDAV or CardDAV service".
For the "Base URL" I tried
https://cloud.disroot.org/remote.php/dav, but none worked.
For "User name", I used my Disroot username (without the @disroot.org at the end).
For "Password", I tried to use my default Disroot password and a generated app password, but they both failed.
What can I do to remedy this problem? Thank you.
