What docker images are you using:
min4tozaki/anchore-engine:1.0.0 (Using filebeat)

Dockerfile for add certificate (Self Signed Certificate)

FROM <IMAGE_ANCHORE_v1>
USER root:root
COPY ./<NEXUS_CERT>.pem   /etc/pki/ca-trust/source/anchors/
COPY ./your_cert.cer /usr/local/lib/python3.8/site-packages/certifi/
COPY ./another_cert.cer /usr/local/lib/python3.8/site-packages/certifi/
RUN cat /usr/local/lib/python3.8/site-packages/certifi/*_cert.cer >> /usr/local/lib/python3.8/site-packages/certifi/cacert.pem
RUN update-ca-trust

How to reproduce the issue:
Anchore deployed in Openshift, with custom deployment not using Helm. Nexus can be accessed from pod openshift since it outside Openshift. I assuming that openshift is in intranet. Here deployment files

Files.zip

Anything else we need to know:
When we do image scanning to the destined nexus registry it always successful

We tried to test using
Curl <DNS_NEXUS>
&
Test SSL Python:

$> python3
>>> import urllib.request
>>> print(urllib.request.urlopen('https://<DNS_NEXUS>/').read())

And both resulted success to port default HTTPS but to 50001 it got error code 400 Bad Request
