NavBaseException upon Sign in (BC)

(5) ShareShare
ReportReport
Posted on by 67

Hello,

I am facing a critical issue after restoring a Business Central on-prem database to a new server. After entering my credentials, I get the following login error

Something went wrong.
Message
not shown because the NavBaseException(string, Exception, bool) constructor was used.
Please wait
while the connection is restored.

The session never opens. Note that the event viewer doesnt contain any error, just a warning also pasted at the end (1).

Note: the BC application was in Version 15.

 

What i've tried:

1. I checked that all accounts have the needed permissions.

2. Cleared Browser cache and tried another.

3. Tried to install version 15 with database version 14, but i got an error "database is too recent"

4. Tried to install BC 18, i get the attached error in this question.

5. Tried to install BC 22 but it says i need to upgrade the database "i still tried to upgrade but it seems it needed a missing dll"

 

(1) The warning in event viewer: 

Message (NavNCLDotNetCreateException): This message had personal data removed. The original may still be in transient telemetry. Find it using the transientTelemetryId.
RootException: NavNCLDotNetCreateException

    Hi, If this is a test environment, try removing all users first, so that the first user to log in will be admin.
     
    Thanks.

    Hello ,
     
    Login hangs because OnOpenCompany runs custom code that tries to load a missing .NET DLL after the server move.
     
    Fix:
     
    Install same BC15 CU as old server
     
    Copy Service\Add-ins from old server
     
    Reinstall any custom DLLs / GAC assemblies
     
    (Optional) Temporarily uninstall the custom app to confirm
     
    Regards,
    Oussama Sabbouh
