failed to fetch https://helm.wso2.com/index.yaml : 403 Forbidden

This previously worked about 3 months ago, no longer does, I'm an architect troubleshooting WSO2-PingFed-mTLS auth for my employer who does have a license however they are too locked down for me to assist.

Q: What is the auth process
Q: Can I use my work credentials for my home lab to troubleshoot
Q: Do you have demo/trial credentials
Q: Is this anonymous and I'm just doing something wrong.

Thanks
