Satellites problem

I have had problems with the satellites for my RBR50v2 since the start but recently it has become worse.

Strangely the system claims that everything is ok when I use orbilogjn on a browser. There all satellites are attached with 5Ghz. I have an RBS50Y in the system also. The distance between the satellites are less then 10 meters. 

In the Orbi app some satellites are offline and I get no wifi coverage on any satellite, only the router.

it works on and off and the routing between the satellites changes randomly.
I replaced my 4G modem with a ZTE 5G router for broadband access. The ZTE is great but can only be configured as router, not as a modem. So I put my Orbi in AP mode.

 

Any suggestions?
