    Could be a caching issue, try it in incognito mode.

    hello Daniele ,

    thanks for early replay, I got to know for Navision but I'm asking for Business central on-Prem, so can I know where the ClientUserSettings.config file is present for BC

    I have changed in the ClientServicesCredentialType to NavUserPassword whiich is there in  "C:\inetpub\wwwroot\<ServerInstance>\navsettings.json".

    hello

    look in the folder search %AppData% (this is for Dynamics NAV 18 , but it is the same for BC on-prem)

    open CLientusersettings.config

    and change the following parameter as on the service:

    AS iS:

    TO be:

    <add key="ClientServicesCredentialType" value="NavUserPassword" />

    check my answer if it helped you, thanks
