Good day, everyone.
I can't update. Latest working releases 6.46.6 and 6.47. Above, when updating, the connection to the Internet disappears and every 5 seconds the connection to the RoS itself disappears. Resetting the settings does not help; after setting the parameters, the situation repeats. The logs are empty.
When dumping, it first reports that it does not support the connection and you need to switch to Legacy Mode, but after a few seconds it connects.

My config:

It may be a configuration problem. Save your configuration script then reset to factory defaults and try the update. If it works then you probably have a problem in your configuration. Install your configuration in chunks using terminal till you find a problem then fix it.

Good time. It did not help, the problem appeared a few minutes after I consistently entered all the settings.
