My comment above and the link there says most of the information you need.
Also I’ve answered for your issue in my repo: Trusting a Custom Certificate Authority (enable https) on running AWX instance currently without SSL support · Issue #284 · kurokobo/awx-on-k3s · GitHub

I have already provided you with enough information, so could you please check the answers first and give it a try?
