Problems with site/languages with custom url

I have a multilingual site https://kaspersky.whiterussian.studio/,
the client proxies to Kaspersky Interactive Portfolio Tool.

I added to the config.php:

'url' => [
    'https://kaspersky.whiterussian.studio/',
    'https://www.kaspersky.com/int_portfolio/'
]

and now not one link works (all pages redirect to home),
even the link to the panel, as well as switching languages.

But on main site all work fine.
