BroadLink RM 4 Hub and placing it inside a closed cabinet

I have purchased the BroadLink rm4 mini
I have linked it to all my devices; Samsung smart tv, audio receiver, Cabel dish,…
They are all located inside a closed cabinet, except for the TV
I placed the rm4 hub in the cabinet too
Everything works great as long as the cabinet is opened.
Once I close it, the hub receives the signal, but I can’t control any of the devises
The cabinet is closed with tilted glass from IKEA

Any suggestions on how can I solve this issue.

And I don’t have a close place outside the cabinet to place the hub
