Has anyone faced this issue, or any solution, suggestions.

Hi @Arun Das -

Did you check to see if your Veeam services are running? See the User Guide for specific services it uses:

https://helpcenter.veeam.com/docs/backup/em/em_components.html?ver=120

Another thing I would check is if the SSL has expired or not for the VEM.  You can update them with new following this - Updating TLS Certificates - Veeam Backup Enterprise Manager Guide

Hi coolsport00,

Yes, services are up and running for both Veeam EA and VBR.

Certificate is up to date with valid expiry date under IIS, am unable to open EA console to check anything.

That screenshot of IIS just shows it is using SSL not that the certificate is expired or not.  If you check the Bindings section you can see the HTTPS and what SSL it is using.

The other option is to uninstall and reinstall VEM pointing to the same DB you are using now so it saves the information or start with a new DB.  This will definitely fix the SSL problems as I have done this many times.

@Arun Das

hello Check in IIS if you have selected the correct certificate.
I personally solved it by changing the certificate in the “Edit  bindings”  on IIS\Sites\VeeamBackup.

@Arun Das -

If you click the “info” icon in your web browser when attempting to connect to EM, you should then be prompted with a few options, 1 will probably say “connection is not secure” or ‘certificate is not valid’. You can then click on one of these to view your certificate to see if it’s expired or not. If expired, you can modify your cert as @Link State shared.

hmm the error clearly states commonname issue, so it should not be expiration.
Couple of questions:

• Did you have some manually made changes to web.config in the previous version, the upgrade overwrites the file to default and thus erases changes (I was a "victim” of this)
• Can you try https://{hostname}:9443 instead of https://{FQDN}:9443
• Which TLS certificate is being served currently (Chris also asked this in a previous post)
  • If its the wrong one, @Link State posted a solution for this
• Is the server domainjoined or not?

While this could be certificate issue, from experience, the fqdn used could pose an issue as well when SSL/TLS certificate is employed unlike when using self-signed certificate

Any solution yet on this … We are facing exactly the same issue after upgrading from 12.0 to 12.1.56

We checked certificates, and all IIS settings... none of them worked.

support couldn't help too...

Nothing I have heard of but as I suggested you can uninstall and reinstall VEM using the same DB to fix it also.

We did a repair/reinstall too - it did not fix the issue.

Did you do an uninstall of everything VEM, reboot and then install again?  I have done this several times using the same DB to fix issues and it works every time.

Hi All,

 Yes, I could resolve this issue, uninstalled and reinstalled VEM using the same DB, I still got the certificate error, regenerated manual certificate and assigned to VEM under IIS.  KB4534: Browser-based Application's Page Fails to Load With: ERR_SSL_KEY_USAGE_INCOMPATIBLE (veeam.com)

Good,

Thanks for the update, you can report the best answer.

@Madi.Cristil @safiya - can you unmark the best answer as it was just asked to mark it so I think it was done in error.  The previous reply by the Author should be the answer.

Had the same issue after upgrading to 12.1.1.56

The Veeam backup site binding on port 9443 was set to the Veeam Self-signed certificate. Manually changed to the Veeam Backup Enterprise Manager server certificate.

Refreshed the page & connected OK

I have seen this as well where the binding gets messed up and this fixes it.  Or a quick uninstall and reinstall too.
