Good catering and hotel management departments can't open it.

There may be a network problem or a restriction.

A good catering and reception catering management system contains some important hotel information, such as hotel information \ customer relationship \ SMS center \ front desk cashier \ catering reservation \ kitchen management \ print monitoring \ wireless interception \ data center \ warehouse management \ room management \ bath management \ report center, etc., so some exclusive restrictions may be set, and the problem is not serious. Secondly, if there is no restriction, it should be a network problem, and the network is running.
