Can't connect to WhatsApp web for more than 5 minutes

[BlackD0127]

After signing in with my phone to WhatsApp Web (Chrome or the windows program), it wants me to sign in again with the QR code after 5 minutes. The phone says that they are connected but not active. Anyone else got this problem?

EDIT: until now, I used WhatsApp Web in Edge, now it does the same thing there.
