MTLS compose example complains certificate

[ekneg54]

if i want to tryout the MTLS compose example I get:

❯ logprep run https://localhost:8082/config/pipeline.yml
InvalidConfigurationError: https://localhost:8082/config/pipeline.yml HTTPSConnectionPool(host='localhost', port=8082): Max retries exceeded with url: /config/pipeline.yml (Caused by SSLError(SSLCertVerificationError(1, "[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for 'localhost'. (_ssl.c:1006)")))

perhaps it is a bug in the certificates or in the MTLS authentication methods itselfs
