<@U03BTNACHNX> sorry I don’t know how to use the API interface，im using self-hosted method to install the signoz to my EKS cluster

Endpoint for Logs API:
`POST` `https://{URL}/api/v3/query_range`
Replace `{URL}` with your instance URL, e.g., <http://example.signoz.io|example.signoz.io>.

the instance URL means the frontend link？

curl -X PORT <http://a0e645362d0fb405fb22ba5258d33505-2034764565.ap-southeast-1.elb.amazonaws.com:3301/api/v3/query_range>
404 page not found

I have solved this problem，thanks   <@U03BTNACHNX>

It’s a simple question, because no data matches. The developer made it easier to print logs, most of which don’t match :joy:
