Failure WLAN at startup terminal or payment

If there is a loss of WLAN (or SIM mobile data) when starting the terminal or for payment, this operation can always be repeated after reconnecting to the Internet.

If the error persists and the signal is available, it may be the unavailability of the authorization host (outage on the part of the terminal operator), a problem with the keys, etc. In this case, it is necessary to contact the helpdesk.
