Unable to establish connection between Radius and Duo Proxy

DuoProxy is unable to establish a connection with the Radius Server.

I am using windows 2012 as a Radius Server and following is the Authproxy.cfg and find the connectivity_tool.log as below.

[main]
debug=true

[radius_client]
host=1.1.1.1 (Radius Server IP)
secret=password (Radius Server Password)

[radius_server_auto]
ikey=000000000
skey=00000000
api_host=■■■■■■■■■■■■■■■■■■■■■■■■
radius_ip_1=1.1.1.1
radius_secret_1=password
failmode=safe
client=radius_client
port=1812
