Failed to connect. (OSError('Tunnel connection failed: 403 Tunnel or SSL Forbidden'))

[zmanhogmail]

Hello,
I am using a windows2019 server to access the AWS, but it returned (OSError('Tunnel connection failed: 403 Tunnel or SSL Forbidden'))

here is the log. would you please help to check? And i have 2 questions:

1. I would like to confirm the aws-adfs is using proxy to connect to the aws. (i have tested my server is able to access the proxy server)
2. my adfs-host is correct? "http://adfsu.ccbb.hk/adfs/ls/idpinitiatedsignon.htm?loginToRp=urn:amazon:webservices"

C:\Users\user1>aws-adfs login --profile my-adfs-profile --adfs-host "http://adfsu.ccbb.hk/adfs/ls/idpinitiatedsignon.htm?loginToRp=urn:amazon:webservices" --no-ssl-verification
