Added ApiController to Ocelot Gateway, but gets 404 when requesting it

[Montago]

This might only be a configuration issue..

I've added an ApiController to my gateway / swagger hub project and enabled GenerateDocsForGatewayItSelf
This now shows my Api:

But when i call it i get a 404

Any ideas why ?

I've been investigating this the whole day and it seems that either Ocelot or MMLib.SwaggerForOcelot is obstructing the default Routing of ASP.NET

I've tried adding custom routes to the Routes config that should point directly to the static files, MvcController or ApiController ... and all of them result in a 90seconds timout and 404 or 503 ..

I've had the same problem with .net8, and Ocelot from 17.0.0 to 23.1.0.

I don't know the reason, but I think it has to do with .net8 and the shortcut to map controllers, in the following image you can see how I got it to work.

Best,

If you do not add a QoS section, QoS will not be used, however Ocelot will default to a 90 seconds timeout on all downstream requests.
