AS iS:

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

TO be:

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".

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