[SOLVED] VBR 11a can not browse AWS S3 Buckets

[dali@iae.nl]

On Windows Server 2019 no problems, but on Windows Server 2022 cannot connect to AWS S3.
Tested on different servers. Now used new created clean 2022 Server + Veeam 11a latest patch P20211211. Firewalls on or off no change.
In the "New Object Storage Repository", "Bucket", when click on the Browse Button is gives: "Failed to list S3 buckets: check if the specified account has required permissions.".
On the same 2022 server, using the S3 Browser and the same credentials there is no problem. Is this a bug?

Does the server has general access to the internet and DNS is working correctly so that it can check the certificates used for the https connection ?

Yes, the 3 certificates can be downloaded without problems (stated in https://www.veeam.com/kb3215). And I did a fresh install of windows 2022 with DNS 1.1.1.1 and downloaded from this server the Veeam ISO and patch.
And also with the renkey S3TLSRevocationCheck = 0 did not help.

Sorry, I can download the certificates on other servers but not on the Win 2022 servers.
Although I cannot download the certificates securely, it seems to be a timing issue as found in the C:\ProgramData\Veeam\Backup\Satellites\VBR\VBR_Administrator\Agent.PublicCloud.Satellite.log file --> "3 error: The difference between the request time and the current time is too large."
Corrected the exact time and now I can list the S3 buckets. Case closed.
