Attachment uploading not working on some pages

Hi team!
I have problem with attachments in some pages in version 14.5 (local installation with tomcat 9, SLES 15-SP3).

Attachments (while editing page, making link and upload file from CKEditor) works fine in page with address
https://xwiki:8443/xwiki/bin/view/Информационные%20системы/XWiki/

But it do not upload from page with address
https://xwiki:8443/xwiki/bin/view/Базы%20данных/Oracle/1_Задачи/Чистка%20SYSAUX/

Does CKEditor attachments uploader sensible to the length of URL or to the characters in URL?

Best regards, Vadim
