When we try ti install packages from nuget api source feed list loads fine but it keeps erroring with the following error
NU1801: Unable to get repository signature information for source https://api.nuget.org/v3-index/repository-signatures/5.0.0/index.json.

Proxy server settings are fine system can reach the internet and can load teh service indexes of all feeds fine.

is the nuget configuration line.

A check in the browser will not be mandatory give the proof for an application. It can be handled by different Firewall rules as well.

let us know more details on how you checked in detail. Also refer to additional resources like Windows event manager for getting more hints on the issue

It can reach in UiPath it self the feeds them selfs it loads the list of compatible stuff for the project.
Even used fidler classic to see what traffic is rolling in an out and there it was shown the server can reach all feeds.

also in cmd tracert and other trafic are flowwing fine by the looks of fidler

is another app, so we cannot assume that everything is handled with the same fw rule.

Which entry is in:

for UiPath-related entries?
