Mobile client "SambaPOS v2.0.54" order taking error

Dear All,
Let me share my Mobile client strange error.
I am using SambaPOS 5.3.6 with using 10 android tablets.
Suddenly it is happening like that:

  1. When we take order from Tablets, it send to Kitchen, But it is not updated into Server PC and not listed in order lists.And we can’t find anywhere those orders taken from Tablets.
  2. When we take order from Server PC, it send to Kitchen and also can be seen in all Tablets.
    So, the error is that it is not updating order from Tablet-to-Server ,but it is updating order from Server-Tablet.
    Could you please suggest me how to solve it?
    Respectfully,
    MD Hasan
