Error connecting Mikrotik hex RB750Gr3 via Winbox

RouterOS General
1

After connecting to Mikrotik via Winbox, I get a blank screen, without a list of interfaces, firewall and other things, after 10 seconds the connection is disconnected.
But I can connect via the web interface, and see in the logs that the connection has occurred and the login is disconnected through Winbox.

This problem is observed on one device out of three, all the same with the same firmware

Router OS 6.47.8
Winbox 3.24

Which version of RouterOS have you installed on the device? For newer versions you need also a newer version of Winbox.

Router OS 6.47.8
Winbox 3.24

I forgot to add that this problem is observed on one device out of three, all the same with the same firmware

Recommend upgrading winbox to latest 3.30
