Earlier, invoices were being sent using NTN, but now this issue has occurred. If I enter NTN, it shows an error, but invoices can be sent using NIC. Why is NTN not working?
this actual FBR response
{
“success”: false,
“message”: “FBR connection error: HTTP request returned status code 401:\n{\n\t\t\t\t\t\t\t\t\t\t\t\t\“dated\”:\“2026-04-16 13:31:36\”,\n\t\t\t\t\t\t\t\t\t\t\t\t\“sourceInvoiceNo\”:\”\“,\n\t\t\t\t\t\t\t\t\t\t\t\t\“validationResponse\”: {\n\t\t\t\t\t (truncated…)\n”
}
working fine at my hand,
