cannot upload with "proxy error"

[w0000641]

I cannot upload log file from web-service.

Splunk said "('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',)) ".

How can I fix it ?

web_service.log

Hi,

have a look at this answer https://answers.splunk.com/answers/210955/data-uploader-why-am-i-receiving-a-cannot-connect.html#ans...

"What happens if you try and set this in splunk-launch.conf
no_proxy=127.0.0.1,localhost"

Greetings,
Jacob
