Forbidden Error (403) with SharePoint Online and KingswaySoft

[JMagDB]

Hi,

We encounter an error when we try to connect on SharePoint Online site with KingswaySoft.

The connection seems to be ok, because if we use wrong password, the server return an error 500.

But, with correct credentials the server return an error 403 Forbidden

We try, with and without proxy, on 2 differents SharePoint Site, on 2 differents computers and with 2 differents Visual Studio.

It works fine, last week.

So, does anyone have an idea ?

Regards

@JMagDB, this is likely related to some recent security profile changes for the connection user. Would you please be able to reach out to the support team by sharing the detailed error message with us?
