github repo seems valid.
I’m not 100% sure what the issue is with HSP and what the changes were, but error most likely points to self-signed cert. Are you using self-signed cert on HSP side?
If you are, please read this forum thread: Allow self-signed certificate TLS-URL in endpointUrl for S3-Backups
You have 3 choices:
- use non-ssl endpoint
- somehow trick backup (by adding your CA to the trusted certs in the docker container)
- wait for [K8SPXC-752] Allow disabling TLS when taking backups - Percona JIRA
