Hi All,
In PBS, While i added my s3 bucket as a remote data store via pmoxs3backuproxy.. Put IP address and port there with s3 access and secret key like picture. However, when I try to add a sync job, I encounter a "remote connection failed" or SSL issue like picture. Could you help me to resolve that.

Hi,
please note: pmoxs3backuproxy is not developed and maintained by Proxmox, this is a third party implementation! Please reach out to the developers for support, they might be able to pinpoint your exact issue. From what I can see I would guess you are using an incorrect fingerprint? Maybe you are not using the one matching the certificate of pmoxs3backuproxy server.

Also: Official S3 support for Proxmox Backup Server is being worked on, so please subscribe to https://bugzilla.proxmox.com/show_bug.cgi?id=2943 to get progress and status updates.
