Try to implement what is mentioned in this post:
https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/

- 28 - Non-ssl (non-https) communication is not permitted by default. It can be enabled in B4A v9+ by adding this line to the manifest editor:
B4X:
CreateResourceFromFile(Macro, Core.NetworkClearText)
Edit: I noted that you are using B4A v.8.5. Try to add this to the manifest:
B4X:
SetApplicationAttribute(android:usesCleartextTraffic, "true")

Thanks for your message.

Add this to the manifest and it does NOT work.

SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:usesCleartextTraffic, "true")

Thanks Erel! I will buy version 9.01 of B4A and see if the error continues and will notify you.
You did not get the point. Http is insecure, Https is secure (encrypted). Android 9 does not allow insecure connections unless you change the setting. It's not an error.

Yes... but... It's VERY important to use RSA/AES (= https) so that the connection is ecrypted. OKHttpUtils does this automatically for you. Otherwise all of the traffic can be hacked/read easily. Take care of it when you publish such an app. Customers will NOT like it and you WILL get into problems.

Another one: I can access your system via my browser just by typing the IP address from your post :D XAMPP ist good for test environments but it's not for production systems.

Note: Of course I will not do anything (but I could).
