Blazor Server app doesn't find/execute the login endpoint when tested outside of Visual Studio

Okay, I have finally found the answer to why this was happening. It's PWA's fault.

This person had the same issue as I.
The solution is to either:

• remove PWA from index.html (Client side) -> remove: <script>navigator.serviceWorker.register('service-worker.js');</script>
• or use PWA but server-render certain endpoints (so in my case api/users/login and some other endpoints) from service-worker.published.js (it's under service-worker.js). You do it by editing this line: const shouldServeIndexHtml = event.request.mode === 'navigate', e.g.:

const shouldServeIndexHtml = event.request.mode === 'navigate' && !event.request.url.includes('/api/users/login') && !event.request.url.includes('/api/users/logout') && !event.request.url.includes('/signin-steam');

It looks like /signin-steam is needed in order for it to properly work. I hope it can help somebody.
