Hi everyone,

I am reaching out to get some help regarding a licensing issue with the Architron plugin for Cinema 4D.

The Problem: Everything was working perfectly until my workstation went offline. Immediately after the internet connection was lost, Architron stopped recognizing my license. It now displays a "No License" error or shows the license as invalid.

My License Details:

Source: My Architron license is the one included as a bundle with my OTOY Octane Subscription.

Status: My Octane Render license is active and working fine, but the Architron plugin specifically seems unable to validate the "seat" while offline.

System Info:

C4D Version: [2025.3.2]

Architron Version: [2025.2]

OS: [Windows 11 ]

What I have tried so far:

Restarted Cinema 4D.

Logged out and back into the OTOY account (when briefly back online).

Verified that the license shows as "Active" in my OTOY account dashboard.

Has anyone else experienced this "offline invalidation" with the bundled version? Is there a specific way to "lease" the license for offline use, or is this a known sync bug between the OTOY subscription and the Architron plugin?

Any advice or workarounds would be greatly appreciated as this is currently halting my workflow.

Best regards,

JOJO[

Update: I should have been more specific. I am currently online and my internet is stable, but Architron still won't recognize the bundled license. It seems like the "license seat" is locked or failed to trigger a re-check after the brief offline period. Does anyone know if there’s a specific cache file or a manual "Refresh License" button for Architron within C4D?

Im Lightwave user......same problem here.....

Yeah, it’s a total nightmare. How did you eventually manage to resolve the issue?

I apologize for this outage.
There were some problems with the OTOY license server, which should now be resolved.

If anyone is still having problems running an OTOY license with Architron or LWCAD, please let me know back.

Please report if this kind of error happens again via OTOY support or directly to me at lwcad.com support.

Regards,
Viktor
