Dont working VIP login with PC

I have stopped working authorization in the VIP system a few months ago (even in incognito mode with all plugins disabled and through different browsers). Up to this point I logged in and used all the functionality of the system. SHiFT account works in a separate site. Also, strangely, the VIP system works on a mobile phone.
Can u help me, plz?
