FAO: Exspress developers - failed sso logins

Former Member over 9 years ago

I was receiving these errors in the Express.log when attempting to log in after adding a device. Using google single sign on, but the same creating a new account also.

2015-11-24 17:23:16.4619 |   1 | I | Unable to exchange sso ticket for token. 

System.Net.Http.HttpRequestException: Response status code does not indicate success: 417 (Expectation failed).

I solved it by adding this section to the express app.config file.

<system.net>

    <settings>

        <servicePointManager expect100Continue="false" />

    </settings>

</system.net>
