Diyhue connection timeout

Hello, I was tried to setup diyHue on my OpenWRT and then on my server using docker but I received error message form Hue Essentials Android app
“Connection timeout has expierd [url=, connection_timeout=3000 ms]”

I received this error when I installed diyHue on OpenWRT as native instance and when I installed diyHue on my server as docker instace.

I can not resolve this issue and I don’t know what should I do?

Please help and best regards,
