Httpx AsyncClient Timeout Error

[EWOgthb]

Hi, we had a strange situation with AsyncClient. Here is the deal;
First of all this situation happened at Windows system. So my coworkers who uses Mac didn't get this error.

When I make request directly (not async) it works fine, it's a basic get request so i get response in milliseconds. But when i use AsyncClient it takes too long to get response, we solved this with setting timeout to 30secs but this shouldn't be the solution. Obviously something goes wrong...

I got WSL2 installed btw. Network connection is looks fine, other services work well (more complex requests) and so on...

Here is the error log;
