Error configuring Nextcloud Desktop on local server over VPN

NethServer Version: 7.9.
Module: Nextcloud

When configuring Nextcloud desktop on Windows 10 through the company’s VPN, it recognizes the server, but when allowing the connection, it is informed that an internal error has occurred, but when configuring the desktop client on a PC that is on the local network, it allows the connection.
Below is the Nextcloud log:

[index] Erro: Exception: OC\Core\Controller\ClientFlowLoginV2Controller::grantPage(): Argument #1 ($stateToken) must be of type string, null given, called in /usr/share/nextcloud/lib/private/AppFramework/Http/Dispatcher.php on line 225 in file ‘/usr/share/nextcloud/core/Controller/ClientFlowLoginV2Controller.php’ line 152 at <>

Why use VPN for accessing NextCloud?

What exact version pls?

Because I am outside the local network, the Nextcloud server is located on a local company server

Nextcloud version is 23

Try updating to the latest version which is 25.


I sorry the version is 25.0.2
