Webdav copy process hangs at 99%

Nextcloud version : 21
Operating system and version : Ubuntu 20.04
Apache or nginx version: nginx latest
PHP version : 7.3

The issue you are facing:

When we mount the nextcloud server on windows via WEBDAV and try to copy files (e.g 900mb) the copy dialogue directly moves to 99% than it gets stuck there like foreever

We tried method eg. We tried with RAIDRIVE and mounted as Nextcloud and also as webdav. The initial problem solved of showing proper program from 0-99%. But it Also get stuck in the last stage (above image).

Can someone please guide on this.

We tried the following.

  1. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRxDAV\Parameters
    increased from 1800 to 3600
  2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
    increased from 50mb to 4gb
  3. Used RAIDRIVE to avoid any windows bug.
