Getting error Failed to connect to instancename.cloud.splunk.com port 8088: Timed out

[swadeepmohanty]

Every time I am getting error when I am trying to run following command:
curl -k https://instancename.cloud.splunk.com:8088/services/collector/event -H "Authorization: Splunk TOKEN" -d '{"event": "hello world"}'
This is my Self-service Splunk Cloud.
Even I tried with Postman with POST method and setting Authorization Key with token as Header, still getting There was an error connecting to https://instancename.cloud.splunk.com//services/collector/event.

Hello @swadeepmohanty ,
what is the exact error you are getting? Try this command:

time curl -k -vvvvv https://instancename.cloud.splunk.com:8088/services/collector/event -H "Authorization: Splunk TOKEN" -d '{"event": "hello world"}'

The prepended time command will show how long does the curl request take. The -vvvvv switch will show verbose info.

Let me know how it went.

By running the command with -vvvvv I am getting the following error:
* upload completely sent off: 8 out of 8 bytes
* Mark bundle as not supporting multiuse

ohh, you're on windows! 🙂
use double quote and escape them in json:

curl -k -vvvvv https://instancename.cloud.splunk.com:8088/services/collector/event -H "Authorization: Splunk TOKEN" -d "{\"event\": \"hello world\"}"

Awesome! It worked. 🙂
