Hi there
I wrote an app about 2 years ago that has been running fine, but this month the published version of the app no longer functions. Each call to an api, although I get a 200, returns html as the response. All calls to the api's return html.
I ran it locally in debug and it works as expected, it's just the published version that doesn't work. I tried remote debugging, but it doesn't load the symbols for the client and that is what I need to debug.
I don't know what caused this behaviour and it's a business critical app. Any help would be appreciated.

Just another point here, I managed to put a breakpoint in the server project. It was never hit when it's the first thing that happens on the index page after you log in.
Another point here, even postman doesn't hit the endpoint. It just returns

it looks the api calls redirect to login rather than return a 401 error on access denied.
