I am working with microsoft bot emulator and everytime I make a request to an external link my office proxy blocks it and application returns 407 error. To work around this I tried following hacks.
Hack #1:
Used fiddler 4 with auto authenticate rule enabled. But I found it doesn't work for ntlm proxy. I also found that the request which are completing with 200 status code has a proxy-authorization header with some encoded content. but I don't know how to set this header for all the requests.
Hack #2: Installed and ran a cntlm proxy, still same error.
I am using Micosoft bot framework 4 with dotnet core and bot emulator 4.10, Os: windows 7
Please help let me know if I can somehow make it work around ntlm proxy.
Looks like the office network is very restricted when it comes to network access.
May be you should better talk to your IT department if you can't get a PC that is located in a different subnet that is less restrictive. Or if you are lucky the change the configuration for your PC so that you can access the required servers without proxy.
