Failed to get the system proxy settings. Calamari will not use any proxy settings


We seem to get this warning whenever we “run a step on the Octopus Deploy server”

“Failed to get the system proxy settings. Calamari will not use any proxy settings.”

The step actually runs just fine on the Octopus Server, but the warning is just annoying.

If you are running the step on the Octopus server it sounds like the server has been configured to use the default proxy, You can find out for sure by running the following on your Octopus server from the Octopus binaries folder (usually C:\Program Files\Octopus Deploy\Octopus):

.\Octopus.Server.exe show-configuration | Select-String -Pattern "Proxy"

You should get a list of proxy settings, I’m guessing that Octopus.Proxy.UseDefaultProxy is set to true. If it is, you can disable the proxy by running:

.\Octopus.Server.exe proxy --proxyEnable=false

If that is not the problem would you mind sending the raw log from one of your deployments ( to and we will investigate further.

Thanks for that. Are you able to edit the page to remove some of the specific of our environment e.g the paths and the usernames.

Thanks Shane
