i am using expo
until now i worked on development mode and everything worked fine, but when switched to preview mode

"preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },

i get “Fetching events failed: Network Error”
i printed this error to the screen

const response = await axiosInstance.get(`/events/by-location`, {}
....
    } catch (error) {
      Alert.alert("Error", `Fetching events failed: ${error.message}`);

the server is running on aws. so its not localhost problem or anything like that.
does anyone has idea why could this happen?
i thought maybe it could be because i use http and not https and android is blocking it, but i saw other people have managed to send http request using expo so i dont think that is the problem.

i tried to check that the http request works in different computers and it did, so the problem is probably not in the server
