When the database file is stored on a remote host accessed through the DAV protocol the file is always opened in read-only mode. If I save the file with a different filename the file stays in write mode until I close it. When I reopen the (second) file it opens in read-only mode. Ownership and file permissions are always the same in both files (opened or closed).

The client used to access the remote file is the built-in Gnome Online Accounts (nextcloud account) which maps the remote location to a local link like: /run/user/1000/gvfs/dav:host={host},ssl=true,user={user},prefix=%2Fremote.php%2Fwebdav/{folder}

Expected Behavior

The file opens in 'rw' mode.

Current Behavior

The file opens in 'ro' mode

Steps to Reproduce

1. Connect to a nextcloud account in Gnome Online Accounts.
2. Using KeePassXC open a .kbdx file from the remote location.
3. The file opens in read-only mode.

Context

This only happens when accessing the database file through Gnome's Online Accounts (which uses the DAV protocol).

Debug Info

KeePassXC - 2.4.3 Revision: 5d6ef0c

Libraries:

• libgcrypt 1.8.1

Operating system: Pop!_OS 18.04 LTS CPU architecture: x86_64 Kernel: 5.0.0-23-generic

Enabled extensions:

• Auto-Type
• Browser Integration
• SSH Agent
• KeeShare (signed and unsigned sharing)
• YubiKey

Closing, as the problem probably lies on the way Gnome Online Accounts client connects to the webdav folder.
