RDM 2026.3.15 – Frequent DVLS Authentication Prompts, Slow Connections, and Freezing

We’ve been experiencing intermittent issues connecting to our Devolutions Server (DVLS) vaults. While these issues were extremely rare in earlier RDM 2026.3 releases, they have become significantly more frequent since upgrading to RDM 2026.3.15.

Users are repeatedly encountering authentication prompts asking them to confirm a new device sign-in, along with “Not connected” errors indicating that RDM is unable to connect to the workspace.

Repeatedly closing RDM and then selecting “Yes, it’s me” often results in extremely slow connection attempts, and RDM will sometimes become unresponsive or freeze during the process. Eventually, after multiple attempts or an extended delay, the connection succeeds, and everything works normally afterward. The issue appears to be primarily during the initial authentication and connection process rather than during normal operation once connected.

I’ve upgraded DVLS to the latest version available to us and rebooted the DVLS server, but neither has resolved the issue.

Our environment:

• RDM: 2026.3.15.0 (64-bit)
• DVLS: 2026.3.11.0
• Operating System: Windows Server 2022 (virtual machine)
• Database: Microsoft SQL Server 2022
• User base: Approximately 200 users, with 25–50 concurrent users

Server performance metrics have remained extremely stable, with no apparent resource constraints or performance degradation that would explain these connection failures.

The timing suggests a possible regression introduced in the RDM 2026.3 releases, particularly 2026.3.15, given the substantial increase in frequency. Updating and rebooting DVLS have made no noticeable difference (sometimes it works and sometimes it doesn’t).

I’ve attached screenshots showing the repeated authentication prompt and subsequent workspace connection failure.

Has anyone else experienced similar behavior with RDM 2026.3 and DVLS? Is Devolutions aware of any authentication, session management, or connection-handling issues introduced in these releases?

We’re particularly interested in whether there are any known issues involving repeated device verification prompts, authentication timeouts, or RDM becoming unresponsive while connecting to DVLS.

Any recommended troubleshooting steps, fixes, or workarounds would be appreciated, as this is becoming increasingly disruptive to our users.

Thanks!
