Refinitiv Data Platform API - ProxyError

We are using Refinitiv Data Platform Api - Python Demo tool in windows environment

However , after running the test script we are getting below error -

---------------------------------------------------------------------------------------------

File ~\dev\dbconda-2022_05-py39-r36\lib\site-packages\requests\adapters.py:513 in send
raise ProxyError(e, request=request)

ProxyError: HTTPSConnectionPool(host='api.refinitiv.com', port=443): Max retries exceeded with url: /auth/oauth2/v1/token (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x0000022E823468E0>: Failed to establish a new connection: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond')))

Could you please advise why this is giving proxy error even after loading proxy on the local environment ?

Best Regard
