Hue essentials can't connect to bridge

Hey guys
so I recently downloaded hue essentials and just can’t get the hue bridge to connect to the app. I tried everything from manual connecting to reinstalling everything. It just shows the connecting screen where there is supposed to be the hue bridge to connect to but it doesn’t work. Same for the manual connection. I try to press the push button on the bridge and it just won’t do.

I hope someone’s got a solution for me… Couse I haven’t got any ideas left

I’ve got a Hue Bridge with all first party Lights, the square one so v2 I think. It is connected to the same router as every other device and works like a charm with the official hue app. Newest software it says for both lights and bridge.

And I forgot, I also used 2 other phones but got the same problem.
I’d love for some help here
