The issue we are facing is that when we run Azure Functions locally, we get stuck up to maybe 500seconds, on the screen(see screenshot). then shows a series of timeout errors.

Note that this only happens when I am at work, meaning there is some issue with the security/network in the office. Because when I run it using tethered mobile data or when I run it at home on my wifi, it runs smoothly. After which the problem is solved for a long time, but we have a lot of developers who is having this issue. The work-around works well but I need to report this to the network team on why it is happening and how we can whitelist something. Also note that before we figured the work-around, we tried downloading: func_cli_x64 , both from that site and using npm or chocolatey. All are having long download times and sometimes unresponsive.

Summary of question: What could be blocking or hindering the azure function test locally run, it seems a network issue as it works when I am using my home or personal internet.

My settings are below:
