ERR_CLEARTEXT_NOT_PERMITTED

Hi. I'm working with Unreal Engine 5.3 and Meta Quest 3. I'm having the following error message when using a web browser within UE5 and connecting to an HTTP url. 

ERR_CLEARTEXT_NOT_PERMITTED

Do you know how can I enable the use of cleartext http traffic? Is it somewhere in the MetaXR Plugin or MetaXRPlatform plugin or would it be somewhere in UE5 Settings or do I need to modify some AndroidManifest.xml somewhere?

I found that someone asked something related here: https://communityforums.atmeta.com/t5/Quest-Development/Having-issue-with-setting-Cleartext-HTTP-traffic-for-development/m-p/777427/highlight/true

Also found some info for Android development here:

https://www.repeato.app/how-to-resolve-cleartext-http-traffic-not-permitted-error-in-android-8-and-above/

 

Any help would be greatly appreciated!

I just came across this myself. In Project Settings, Advanced APK Packaging, in Extra Tags for <application> node add the following:

android:usesCleartextTraffic="true"
