Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))

[CloudViking86]

Hello,

First time trying out this project so I might have missed something but I don't believe I have.
Running v.2.0.1 from Windows 10 (Ver: 21H2 Build: 19044.1586)

Trying to login against our ADFS by running (in PowerShell);
aws-adfs login --adfs-host=https://sso.mycompany.com/adfs/ls/idpInitiatedSignOn.aspx?loginToRp=urn:my:urn --role-arn=<our-arn> --region=eu-west-1

but this fails directly with the following error:

Entering the same URL as I enter when launching aws-adfs in my browser;
https://sso.mycompany.com/adfs/ls/idpInitiatedSignOn.aspx?loginToRp=urn:my:urn
then I get directed to AWS and is prompted to select a role.

If I try and use the Windows equivalent of curl - Invoke-WebRequest - I get a "200" response;
Invoke-Webrequest -Method GET -Uri https://sso.mycompany.com/adfs/ls/idpInitiatedSignOn.aspx?loginToRp=urn:my:urn -UseBasicParsing

So the URL is reachable and good and works using a browser, why can't I access it when using aws-adfs?

Sorry if this is something elementary.

Best Regards

--adfs-host is looking for a host name, not a URL. try
--adfs-host=sso.mycompany.com
