Login not working properly

[SiKreuz]

Steps to Reproduce

1. Go through the login process
2. See the error message in the end

Problem

The login verification fails. So the status returned here is a verificationfail

Campus-Android/app/src/main/java/de/tum/in/tumcampusapp/component/ui/onboarding/OnboardingExtrasFragment.kt

Line 134 in 105b81f

val status = tumCabeClient.verifyKey()

I have no idea why this happens. Sometimes a restart helps and I'm logged in, sometimes it doesn't.
This error happens on my phone, as well as on a virtual device, so it seems to be platform independent.

Environment

• Phone: OnePlus 5T
• OS version: OxygenOS 10.0.1
• TUM Campus App version: v3.9
• Language: German and English

I'm also getting this toast:

Campus-Android/app/src/main/java/de/tum/in/tumcampusapp/component/ui/onboarding/OnboardingExtrasFragment.kt

Line 124 in 105b81f

Utils.showToastOnUIThread(requireActivity(), R.string.error_setup_chat_member)

Seems to be a backend thing. @kordianbruck did you change something when experimenting with the new server setup or are there any helpful logs?

Apparently this is the underlying issue:
Uncaught Error: Class 'Crypt_RSA' not found in /app/App/Model/Device.php:47

For context: backend was missing a dependency for using RSA functions.
