What happened to the program? It throws it asks me to log in again through the number and every time with a one-time password, it's so inconvenient that it drives me crazy. Everything was normal... admin, answer what to do???? It's not written that it's a reboot, but it just throws it out, I have to log in again every 2 minutes ?
