Issues upgrading DVLS to 2025.1.9.0

Hi everyone,

I'm currently running DVLS version 2024.3.8.0, along with authentication via Entra ID. All is working correctly.

Today I attempted to upgrade DVLS to version 2025.1.9.0. After the upgrade, the DVLS Scheduler service wasn't able to start anymore.
I rolled back to the last Stable release, 2024.3.17.0, which was successful and the Scheduler service was running again.
However, this broke the authentication via Entra ID.
The following error was shown in the logs:
OAuthTokenEndpointException - OAuth token endpoint error: {"error":"invalid_client","error_description":"AADSTS700025: Client is public so neither 'client_assertion' nor 'client_secret' should be presented."}

I saw the same error here:
DVLS with EntraID App Proxy experiencing OAuth token endpoint error
However, there is no update on this thread or a solution.

So I manually redownloaded DVLS version 2024.3.8.0 and downgraded to this one. And everything is up and running again.

However, I also noticed an issue with licensing. During the upgrade, my Gateway license was invalidated. We've checked our firewall logs, adjusted some rules and the Gateway license is usable once again.

Also, while trying to be prepared for the DVLS upgrade, I've upgraded RDM to version 2025.1.38.0.
When DVLS was back online, my RDM license was invalidated.
Rolling RDM back to 2024.3.31.0 fixed the licensing issue.

I saw in the release notes that, since DVLS 2025.1.3.0, the license validation URL was changed.
We've checked together with my colleagues and the connection is allowed (no blocked traffic) to the new URL. But still, the license did not get validated.

Any help in clarifying the issue will be greatly appreciated!

All the best,
Victor.
