Hi,

I updated one of my backup servers to PBS4.0 to take advantage of the S3 upload feature - super happy about this!
I tested it using Backblaze B2 and I can run a sync job without issues.
I tried adding a Mega 'S4' endpoint and it adds itself successfully (needed to enable 'Path Style'). But I receive the following error when running a sync job (appears on every object):

2025-08-07T11:08:27-04:00: sync group ct/4300 failed - group lock failed: missing header 'date'
2025-08-07T11:08:27-04:00: create_locked_backup_group failed

Has anyone run into this same error? proxmox-backup-manager s3 check with the endpoint and bucket ID doesn't report any issues.
Please let me know if I can add any additional information.

Thanks!
 
Hi, thanks for the report! Seems to be an incompatibility with that provider. I will see if we can introduce an exception for this.
