iOS and Andriod act as proxies, as does something on a mac or pc. Where are you running the sim? A mac or pc?
I'm not sue about this, but the sim may still use the stuff from Internet Explorer in the background. When you tried a browser, which one did you use?
mozila firefox
Your machine should have IE and Edge. Try them. I haven't used firefox in a number of years. It's mainly chrome for me.
it works even in explorer/edge
Check your proxy settings regardless. But you'll probably need to start debugging with tcpdump and/or mitm-proxy or similar tools.
Since this has been narrowed down to the sim (or maybe the sim and iOS), what to you see in "File>View HTTP Traffic" in the sim? Maybe you said that already but worth another try.
Yeah i checked it and it is empty
Could it be some network settings that prevent requests from happening, i remember experimenting with network quality setting, but now I could not find that.
