Running ASP.NET 3.0 Identity behind WAP (Web Application Proxy)

Question

User1326661867 posted

I cannot authenticate from an external client (browser) to an internal ASP.NET 3.0 web site, where authentication is using IdentityServer 4.

The web site is behind a Microsoft WAP (Web Application Proxy).

I get a:  503 - Service Unavailable

Is this by design?
Are there option to authenticate in such an environment?

Thankx, Harry

A 503 error means the service is under maintenance or too busy to respond.  Can you explain how your application works?  What does internal and external mean in your application?  Intranet/Internet?

Thankx mgebhard for your feedback.

internal = intranet | external = internet

I can authenticate, when I am internal, but I can't when I am external. The traffic has do go through WAP (web application proxy).
The following URL gets a 503 response when external, from internal it returns the result (200)

I'm not sure how this is an ASP.NET question.  I believe you need networking or Windows Server support.

Thankx mgebhard.

You have probably right. That is mostly the problem when the issue is not related to just one product.

But at least, there could be users around, which have a similar setup and maybe have it working, or tried and did not find a solution.
Or the ASP.NET team knows about this issue and knows how to solve it, or not ;-)

Thankx, again.
