Empty reply from server with aiohttp with python 3.8

I'm trying to make aiohttp work, tho the simplest code possible is not working. The issue is only present on a specific development server, which is compiled from source.

The following code produces the following output:

from aiohttp import web

async def hello(request):
    return web.Response(text="Hello, world")

app = web.Application()
app.add_routes([web.get('/', hello)])

web.run_app(app)

And I get an empty reply from the server (wget produces the same output)

# ./curl-amd64 http://localhost:8080/ -v
*   Trying 127.0.0.1:8080...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET / HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.75.0
> Accept: */*
>
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer

Im running python 3.8.1 on a custom built linux kernel 5.3.18. Pip is available on the local system. When I run pip install aiohttp, all dependencies are met response is received.

# pip install aiohttp

This issue is only present on this specific system. When I copy the code to a different machine (e.g. mac) the server is responding fine.

Is there anything, that might be missing from the system (system library, shared module etc.) which might be causing this issue?
