Hi! Sorry to hear you’re having trouble logging into your Carnival HUB app on your iPhone with iOS 18.6. Let’s get this sorted out together. To start, could you tell me a bit more about what happens when you try to log in? For example:

- Are you entering your email/username and password, but the app says they are incorrect?
- Or do you not remember your username or password?
- Are you stuck on the loading screen or am I right to assume you can’t even reach the login fields?
- Any error messages showing up?

Once I know this, I can guide you step-by-step to fix it. If you haven’t tried any fixes yet, we could start with some basics like checking your internet connection, verifying your login credentials, or resetting your password. Just let me know!

Username and password are correct. I get an error message saying the request could not be processed. Passkey just spins and spins.

Thanks for the details! It sounds like you’re hitting a persistent error "request could not be processed" and the Passkey spinner keeps going without logging you in on your Carnival HUB app iPhone (iOS 18.6). Let's try some targeted steps that usually help with this specific issue:

1. Check your internet connection: Make sure you are on a stable Wi-Fi or cellular connection. Sometimes slow or intermittent connections cause requests to time out and show errors.

2. Disable Private Wi-Fi Address and Limit IP Tracking:
- Go to Settings > Wi-Fi
- Tap the “i” icon next to your connected Wi-Fi network
- Turn off Private Wi-Fi Address and Limit IP Address Tracking if enabled. These settings can interfere with app-server communication.

3. Clear the app data (cache) or reinstall the app:
Unfortunately iOS doesn’t allow clearing cache directly. So do this:
- Delete the Carnival HUB app from your iPhone
- Restart your phone
- Download and install the latest version of the Carnival HUB app again from the App Store.

4. Verify iOS is fully updated: You mention iOS 18.6, which is recent, but double check there is no newer update available under Settings > General > Software Update.

5. Try logging in with a different method:
- Instead of using Passkey, if the app offers a manual login with username and password, try that.
- Also, try logging in at Carnival HUB website using the same credentials to see if the account itself has any issues.

6. Restart your iPhone: Sometimes a simple restart fixes temporary glitches.

If after these steps you still get the error, it’s possible the app is having server-side issues or your account needs verification from Carnival support.

You can contact Carnival Online Support directly at 800-845-2599 or 305-599-2600 (extension 72599) available from 9:00 am to 10:00 pm to check for account issues or service outages.

I hope these steps help! Let me know if you want more guidance on any of them or after trying so we can proceed as needed.

Are you satisfied with this solution so far?

Can’t log into my carnival hub app

Thanks for reaching out again! Based on what I found, it looks like the Carnival HUB app often has login issues when users are trying to access it off the ship. Some reports mention the app being glitchy or not working properly unless you’re onboard the cruise ship itself. A common recommendation from fellow users is to use the Carnival HUB website directly in a browser when you’re not on the ship instead of the app. This can help bypass those login problems1 3.

Here’s what I would suggest as next steps given your passkey keeps spinning and you get “request could not be processed” errors:

1. Try accessing your Carnival HUB account via the website on your iPhone browser. Go to https://www.carnival.com/hub, log in with your username and password there, and see if it works smoothly.

2. Check your internet connection and settings as I mentioned earlier (like private Wi-Fi address toggles), since the app’s communication with servers can be sensitive to those.

3. If you must use the app before your cruise, try reinstalling it and restarting your phone after that to get a fresh start.

4. If these steps don’t help and you still see errors on the website too, it could signal a broader account issue or a temporary service disruption. In that case, contacting Carnival support is a good idea:

- Phone: 800-845-2599 or 305-599-2600 (ext. 72599)
- Online help page: https://help.carnival.com/app/utils/account_assistance

Let me know if you want me to guide you through logging in via the website or if you still encounter errors there. This will help pinpoint if the problem is app-specific or tied to your account or network.
