Hi!
Since the update to RDM 2025.3.32.0 and DVLS 2025.3.16.0, when we try to create a Devolutions Send link from RDM, it shows the error "Der Dienst konnte nicht authentifiziert werden". I guess it comes from the German .NET Runtime, but it translates to "The service could not be authenticated". I found some posts online mentioning a .NET error "The caller was not authenticated by the service", so maybe that's the original English message. In the DVLS Event Log I see "DevolutionsSendGeneralException - Der Dienst konnte nicht authentifiziert werden".
It works when creating the link on DVLS Web interface, but not in RDM.
The IIS log file shows a successful POST request to DVLS at /api/devolutions-send/create-link-with-file
Can you help me troubleshoot further?
Thank you!
Hello,
Thank you for reaching out to us regarding this,
Are there any additional logs provided from RDM under "Help" -> "Application Logs"?
Could you provide a screenshot of the error you're seeing?
Let me know,
Best regards,

Hi!
Thank you! There's no entry in Application Logs, this is how the message appears:

Hello,
Thank you for your reply,
Are you encountering this issue when using the "Devolutions Sends" option under the 'Tools' section, or when using the "Send" option on an entry directly?
Are all your colleagues having the same problem?
Let me know,
Best regards,

Hi!
The error appears when the window has been opened from both the tools menu and send icon on an entry.
It's the same on multiple clients/users.
Thanks!

Hello,
Thank you for your reply,
I see, could you confirm that the endpoint used for Devolutions Send is not being blocked?

Hi!
I confirmed the network is not the issue. RDM doesn't even try to connect to the internet - it only connects to DVLS.
Each time I click on "Send link", DVLS successfully connects to https://login.devolutions.com and https://quoting.devolutions.com consecutively (I see a few packets of encrypted HTTPS traffic on the wire)
Thank you!
