This was fixed by setting Dead code Stripping to no. Thanks to the Solar2d team for finding this.

The problem is real, either a configuration error or an Xcode bug. I have tried different versions of Xcode (15.1 and 15.4 RC) to no effect. I don’t know how to resolve this. Again, please note the very important distinction: Everything works fine on direct Xcode->device build/install. Everything works fine on Xcode->iphone simulator. Only the archive build is leaving out the network.

Sorry, to be more precise, you will see an access error, but not a system network error if it builds properly.

I have made a zip of the project if you want to see what is happening. You can install but not actually use the app because the content is subscription content, but it should start without an error. The zip file is SScape3.zip. it is at ideategames.org but I cannot put the link because " is not a permitted domain on this forums" (I assume because the word game is in the title, even though almost all my apps are educational).

I am having the same problem, but none of those suggestions have worked for me. I am able to install my packages on my iPad, running 16.6.1, but not on my iPhone X, running 17.1.2. Every time I get invalid ipa. An interesting other symptom is that when the device pairs with Xcode, all of the installed applications show up, but none of their icons show up. I can delete applications from Xcode, but cannot install any, even if I delete the old version first. I have tried everything listed above, several times, nothing helps. Getting ready to throw the iPhone through the window.
