Help/Support Authentication error in app: “Raft Survival - Ocean Nomad”

[rce22 0]

I have several iOSGods apps working perfectly, but with this game “Raft Survival - Ocean Nomad”, I’ve tried all the available versions on iOSGods (the normal one, the one with hacks, etc.), and I just can’t get it to work.

When I try to open it, I get this error: “Attention! An authentication error has occurred. Please check if Game Center is enabled in your device settings, reload or reinstall the game. Continue without saving progress?”

I’ve tried everything the error message suggests, but it still doesn’t work. Other times, the game gets stuck on the first screen and won’t let me press “Continue”. I also tried installing it over the original App Store version, but it just closes automatically.

I’m not sure how to make it work — I’d really appreciate any help or advice with this issue. Thanks a lot in advance!

Best regards.

Hello, Are you sideloading the ipa to install? Sideloaded games don't have the ability to connect to game center. Please read this:

Hola, ¿estás cargando la ipa para instalarla? Los juegos cargados en el lateral no tienen la capacidad de conectarse al centro de juegos. Por favor, lea esto:

 

Thank you very much for your reply. I’m using Signulous — I’ve uninstalled everything, restarted my phone, and repeated the whole process again.

 

In the Signulous app library, there are also two versions of the game. I downloaded both, and here’s what happens:

The game opens, the iOSGods ads appear, it logs into my iOSGods account just like in other games, and I keep pressing “Continue” on the start screen until it asks to “Sign in with Apple.”

This part works exactly like other iOSGods apps such as Subnautica — everything looks normal up to that point.

 

But when I sign in, nothing happens — it stays on the same screen. If I press “Continue” again, it asks me to sign in with Apple once more. I do it again, and it just stays stuck there…

 

I also tried downloading it from the iOSGods “app” and then signing it using Signulous with the “Upload & Sign App” option, but the exact same thing happens.

 

I’m not sure if there’s a way to make it work using only Signulous, since other iOSGods games work perfectly fine. Thank you again so much for your help!!

 

Best regards.

Hmm, are you able to press cancel when it asks for Apple sign in? You can also try downloading ipa from iOSGods and signing with signulous but if those don’t work I would think that it’s on signulous’ end but I could be wrong. As it’s a separate site I don’t have information on their certificates or signing methods. Try contacting their support if needed.
