I am working on a flutter project with mongoDB, there is no big deal at project I just want to SignUp user, but application works only on debug mode and with my mobile Hotspot. otherwise I just click signUp button and I wait long time, then ********** "SocketException: Connection timed out (OS Error: Connection timed out, errno = 110), address = 10.76.236.118, port = 44670". *********** this error throw. I work with real device android Samsung Galaxy A50 (SM-A505F), I don't think there's any error in the codes. Because it works when debug specific IP(when I use my mobile hotspot).However, let me share the screenshot of the relevant parts. what are the things I don't know ,about IP or mongoDB or ....

If you work with a real device, your phone and your laptop have to be connected to the same internet. This is solution for me. Dont't forget add " " at ./android/app/src/main/AndroidManifest.xml
