I am setting up connection for the Splunk instance and Splunk Cloud Gateway via a proxy. Proxy server is basically set to
allow all, Splunk Cloud Gateway is installed on search head.
According to the guideline in Troubleshoot Splunk Cloud Gateway Connection Issues,
for https connection, it can return
curl https://prod.spacebridge.spl.mobi/health_check -x http://my_proxy_svr:8000
for wss connection, it can return
101 Switching Protocols
curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: prod.spacebridge.spl.mobi" -H "Origin: https://prod.spacebridge.spl.mobi"; -H "Authorization: xyz" https://prod.spacebridge.spl.mobi/mobile -x http://my_proxy_svr:8000
However, the status shown in Cloud Gateway Status Dashboard keep showing "Not Connected". For loggings in search, once restarting splunkd, the proxies config is read into program at first but become empty after first "handshake failed" occurred.
May I know if there is any clue why cloudgateway is not connected? Thank you.
