403:AuthenticationUnsuccessful



I've checked, on server - callback, code and state are being received,

I've only one organization.. which I am selecting .. and only one App .. I've tried it with multiple trials and paid accounts

I have VM on an IP with HTTPS (raw IP, not a domain like www.domain.com)... is it causing the problem.. It is working fine in local machine ...

Is the absence of proper domain name causing the error ..pls help

---------------------
I've tried this,

try
SecurityProtocolType.Tls12;
var xeroToken = (XeroOAuth2Token)await _XeroClient.RequestXeroTokenAsync(code);

List Tenant tenants = await _XeroClient.GetConnectionsAsync(xeroToken)
Tenant firstTenant = tenants |0|
TokenUtilities.StoreToken(xeroToken)

catch
