Veeam 11a (and below) on Windows Server 2022

[stanthewizzard]

Hello all

Installation went well
BUT Veeam Backup Enterprise Manager was inaccessible either in HTTP nor HTTPS

I went to IIS
Sites
VeeamBackup
Binding https
double click

Disable where it says disable (tls 1.3, tls legacy, ocsp stapling etc ... )

It works again fot HTTPS and HTTP

Cheers

Hi Stan,

Thanks for information, I'll ask my colleagues from QA to check this scenario.

Thanks!

Hello,

@stanthewizzard
My colleagues didn't manage to reproduce the issue, the scenario works perfectly out of the box. May I ask you to clarify the version of IIS and the exact build of Windows?

Thanks!

Windows Server 2022 Datacenter
20348.288
IIS embed in this version

Hello,

@stanthewizzard
Did you install Veeam B&R from scratch or did you upgrade to 11a from another version? For example, my colleagues have managed to reproduce this behavior in upgrade scenario only.

Thanks!

[stanthewizzard]

Yes upgrade

Hello,

We've completed the research and the following conditions must be fulfilled to reproduce the problem:
1. Upgrade is performed from the version 10 to the version 11 or an old self-signed certificate generated during v10 install is selected in this wizard step during clean installation of v11
2. Upgrade or installation is carried out on Windows Server 2022

The workaround described in the first post is a totally valid approach to resolve the issue. @stanthewizzard thanks once again for the feedback!

Thanks!
