HTTP Request - The proxy server isn't responding

Hi Everyone!

I wanted to call a webservice with HTTP Request from UiPath Studio, and it works great from my computer, but when we want to put it on a server that’s using a proxy, it constantly gets a ‘StatusCode’=0.

I’ve checked if I can reach that service from a browser. The interesting thing is that Firefox can get a response, while IE11 gets “The proxy server isn’t responding” message.

Have you faced a similar issue? Do you have any ideas on what we should check either between the proxy settings, or what we should do within UiPath/Runtime Resources to make it work?

Thank you!
