Home Assistant stops working after a while on Windows 10

Ill try to describe the issue as simply as possible.
Homeassistant loads and initiates successfully but after a while the following exception happens:

2020-07-26 16:37:08 ERROR (MainThread) [homeassistant] Error doing job: Accept failed on a socket
Traceback (most recent call last):

After this, any attempt to connect to localhost:8123 gets a “connection refused”. Things revive via a manual restart only.
Version is 0.113.0 but it also happens on previous versions. Network issues are highly unlike to be causing this - same configuration on the same network works perfectly on a Raspberry Pi

Any ideas?

Hi,
I experienced the same problem for a month or two. Finally fixed it by adjusting the network card configuration as epxlained here http://backupchain.com/i/how-to-fix-error-64-the-specified-network-name-is-no-longer-available

thanks, switched to ubuntu so no more windows for me. I had tried the above too, it didn’t work. By the way this issue is reported as a bug in the aiohttp server component.
