Internet Explorer Expert Info (Chat/Sequence): HTTP/1.1 401 Unauthorized\r\n

Nextcloud version (13,14,15)(any of the versions)
Operating system and version _(openSUSE Leap 15),(SLES 12 SP3)
Apache or nginx version _(Apache 2.4.3),(2.4.23)
PHP version _(7.2.5),(7.0.7)

I ask for your help.
I am a novice and do not judge strictly.
The following problem:
when the user copies the link of the shared folder and inserts Internet Explorer 11 into the browser or goes on the link in the IE11 browser, the site is not opened (the redirect is not performed), but offers to download the file. If the user was logged in to NC, then the inserted link will open. This problem is only with windows Internet Explorer. Other browsers work fine, open the inserted link with the input of the login and password.

I have 2 NC deployed with versions 13 and 15. Version 15 is fresh. Next, I updated version 13 to version 14. and All versions have the same problem.
I tried to find a solution on the forums, but I could not find a solution.
Help.
