Error Codes⚓︎

Code Meaning Next Steps
1 Message Center Not Initialised The Mobile SDK could not enrol at the Message Center. Check that your Message Center is reachable and that the config string corresponds to the one you received from nextAuth for that Message Center URI.
16 Network Client Closed
17 Network Client Not Closed
18 Network Client Invalid Message Type
32 QR Parsing Error The QR code could not be parsed.
33 QR Unknown Type
34 No Accounts Found for Server The user scanned a login QR code (pointing to a specific server), but has no accounts in the Mobile SDK for that server.
35 Display Name Already Exists The server forbids (in its server parameters) two accounts with the same display name to be registered by the Mobile SDK. The user already has an account with this server for the given display name in the Mobile SDK and can hence not register another.
36 No Input Proto
37 Wrong Confirmation
38 Unknown Account
39 Unknown Server
40 Single Account The Mobile SDK is configured to be used in a single account setup and does not allow for more than one account to be registered. Check that the Mobile SDK has no accounts.
41 Enrol QR Expired The QR code for registration is no longer valid: it has either expired or was already used before to register an account.
48 Server Authentication Failed Something went wrong while trying to authenticate the user at the nextAuth Server. Check that the account (for authenticating the user) still exists at the server.
49 Server Authentication Error
50 Server Authentication Timeout
51 Server Authentication Unknown Error
52 Server Not Allowed
64 Server Parameters No Result After scanning a registration QR code, the Mobile SDK could not connect to your nextAuth Server for fetching the server parameters. Check that your nextAuth Server is reachable.
65 Server Parameters Wrong Header
66 Server Parameters No Message
67 Server Parameters Parse Error
68 Server Parameters Hash Incorrect The hash of the server parameters does not correspond to the hash included in the registration QR code. This can happen when the server parameters are updated after the registration QR code was generated.
69 Server Parameters Invalid Signature
70 Server Parameters Timeout
80 Push Decrypt Fail The received encrypted push message failed to decrypt.
96 Second Factor No Valid Server The used Second Factor Server is not allowed by the nextAuth server. Check that the Second Factor Server corresponding to the app's config string is allowed in the nextAuth server for the (virtual) server at which the user is trying to authenticate.
97 Second Factor Timestamp Failure There was too much time between the beginning of the second factor verification process (asking the user to provide his/her second factor) and the actual verification with the Second Factor Server.
98 Cannot Set Biometric A biometric cannot be set since the current PIN is blocked (the process requires user confirmation by input of the current PIN).
99 Cannot Change PIN The PIN cannot be changed since the current PIN is blocked (or not set) and no biometrics are registered as a second factor inside the nextAuth Mobile SDK (the process requires user confirmation either by input of the current PIN or biometric).
100 User Input Required The mobile SDK is still waiting for user input and can currently not process your request (since handling your request will also require user input).
101 Biometric Already Set
102 Biometric Not Set
256 Invalid/Unexpected Command
257 Invalid Argument
