Nextcloud Client doesnt connect

Hello everybody!
Could you help, please?
After installation of Nextcloud Client for mac (last version from site), I cannot connect to server https://cloud.adluxe.ru/
After I push “next” I see just white screen and thats all.
OS - macos 10.14
On my windows computer it works properly. Please, help.

Maybe Adluxe Cloud (full path)?

Unfortunately, it doesn’t work(
It returnes error “cant connect to… unknown error”%D0%91%D0%B5%D0%B7%20%D0%BD%D0%B0%D0%B7%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F%20(1)|690x390

Do you use the white and dark theme? That will be sometimes the problem for showing wrong webpages.

I tried this software on 2 mac computers, one was with dark theme, another white. the result was the same…
