Docker Windows | x509: certificate is not valid for any names

Question

I am pushing OTEL traces to splunk and facing below error.

{"kind": "exporter", "name": "splunk_hec", "error": "Post \https://prd-p-fyu1e.splunkcloud.com:8088/services/collector\: x509: certificate signed by unknown authority, but wanted to match prd-p-fyu1e.splunkcloud.com", "interval": "29.295443106s"}

I am using windows dockers desktop. Any pointers what is missing

Answer 1

I guess you are using splunkhecexporter, so disable cert verification:

insecure_skip_verify: true

Apparently, Splunk cloud doesn't use correct TLS cert from well known CA in this case.
