If you are using Archicad 24 Update 3 or earlier, you may see an “Invalid Certificate” warning when accessing BIMcloud SaaS from March 21, 2026.
Why does this happen?
This warning appears because we have updated our security certificates to align with the latest security standards. Older Archicad versions have limited support for these newer security protocols, which may cause them to display this message.
Is my connection secure?
Yes. Your connection to BIMcloud SaaS remains secure and fully functional with any Archicad versions, and you can continue working on your Teamwork projects without any interruption.
How can I avoid this warning?
If you would like to avoid seeing this message, we recommend updating to Archicad 24 Update 4 or a later version, where this warning no longer appears.
We also recommend keeping your Archicad version up to date to ensure the best overall experience, including the latest features, performance improvements, and security updates.
What should I do if I see this warning?
No action is required. You can safely continue working as usual.
