Hello,

Our server is currently self hosted and we’re trying to implement SSO on discourse app with our .net hosted platform.

Here is the issue we’ve been facing. Could you please forward us to the right direction?

**Failed to handle exception in exception app middleware : Invalid URI:**

In order to help debug your issue we’ll need to know a lot more information please.

Which Discourse version are you running?

At which stage of the authentication process does it fail?

What data was POSTed in order to generate this error?

What else can you tell us?

Look like you’re trying the [OAuth2 solution](https://meta.discourse.org/t/oauth2-basic-support/33879) not [DiscourseConnect](https://meta.discourse.org/t/13045?silent=true), are you missing anything in your .net application that acts as an OAuth2 server?

Hi Richie Rich,  
The discourse version we’re using is 2.8.0.beta1  
I’m not sure about the exact stage of authentication, but if it helps I’ve attached the error log we’ve received.

 ![Screenshot 2021-06-04 at 9.01.45 AM](https://global.discourse-cdn.com/meta/original/3X/c/1/c1fb4a783c72e3c484c14d587b5f2f5c542ddcc3.png)  
And @hawm yes we’re using OAuth2 solution. Which one is easier in your view?

I don’t use the OAuth2 solution for my application, so it’s hard to say which is easier.

The problem in the OP, I thinks your `oauth2_user_json_url` setting is the cause.

The problem was with token. This issue has been resolved by first integrating with google authentication, then we checked what didn’t work with out server. Thank you for your help.
