Problem with AWS Elemental MediaLive Workflow Wizard, Error OutputDataBackground failed to send file for URL [mediapackage]

I am using AWS media live workflow wizard for creating the channel and OTT live feeds. It has been successully created. I am using OBS software for sending RTMP push to Media Live. Connection also established. But HLS ingest point is giving below error.

Cannot load https://c75a7e79204e539d.mediapackage.us-east-1.amazonaws.com/out/v1/070112deeb2945b4b135134ce269fc73/CMAF_HLS/index.m3u8HTTP response code:0 This might be a CORS issue, consider installing Allow-Control-Allow-Origin Chrome Extension

I did try installing chrome extension for CORS, disbale firewall, switched to different browsers.

But error is same.

In the cloudwatch notification for channel, I am getting alerts

OutputDataBackground failed to send file for URL [mediapackage://LiveChan1/channel_emp_240p30_20220805T200336_00298.ts], after [3] attempts, error [failed to write output to mediapackage]
