Why getting 401 error while sending Spans to SignalFx(Splunk Observability as a cloud)?

[glingaraj]

Hi Team,

I have created a trial account in Splunk Observability as a cloud for checking traces and spans. While trying to send spans from an Java based application from EC2 instance(Personal account) using Java agent, I am getting 401 unauthorized error. Have verified creating API tokens as per the documentation but still getting same error. 

Can you please help in suggesting way forward for this issue?
