WebDAV interface may be damaged

Hello,

I have problem with NC server -

The web server is not yet properly configured enough to allow file synchronization because the WebDAV interface may be damaged.

I check 2 solution:

Solution 1

The Windows WebDAV Client might not support Server Name Indication (SNI) on encrypted connections. If you encounter an error mounting an SSL-encrypted Nextcloud instance, contact your provider about assigning a dedicated IP address for your SSL-based server.

Solution 2

The Windows WebDAV Client might not support TSLv1.1 / TSLv1.2 connections. If you have restricted your server config to only provide TLSv1.1 and above the connection to your server might fail. Please refer to the WinHTTP documentation for further information.

S1 - Certificate is same, and valid, date ok
S2 - we have TSLv1.2

Here is log from error:

1. OCP\App\AppPathNotFoundException: Could not find path for spreed

||2. Log Nextcloud|
