Today lost winbox functions 6.47.1 !?

Hello.
I have 2 routers works in conjunction. 1 SXT LTE kit. 2 hAP ac2. Both installed 6.47.1 version of ROS.
Today!! i’m lost functionality of winbox on both of them. I can connect to routers by winbox, but
can’t see nothing on log, on firewall rules and other options. But all working. Even EoIP with IPsec.
But i can’t see never in winbox. What can it be ? Other routers with same functions working,
but ROS have lower version. Is this time bomb in 6.47.1 ?
T.U.

6.47.1 is working fine with WinBox on both my routers. Did you change anything?

thanks for reply. theme closed. problem of cell provider solved. too low speed connection because of traffic limit.
