Error: "Error happened while connecting to project"

[Istvan Moharos]

Related versions: v19 and newer

Possible reasons based on the frequency of occurrence

Archicad or BIMcloud / BIMcloud Basic is not up-to-date 

Make sure that all Archicad clients and BIMcloud / BIMcloud Basic components are updated to the latest build.

Network issue

Archicad must be able to communicate with BIMcloud / BIMcloud Basic to provide Teamwork. To verify this, run the Network Diagnostic Tool from the Open / Join dialog or the Teamwork Palette. Verify whether all necessary ports are open and the server machine is available from the client machine.

User Cache is corrupted

It is possible that current downloaded data have become corrupted, and thus are out of sync with BIMcloud / BIMcloud Basic. On the affected computer, try to leave all joined Teamwork projects.

Local Cache is corrupted

When more than one user is working from the same machine, leaving all joined Teamwork projects may be not enough. Delete the Local Data with the Local Data Manager.

Please Note

Local Data deletion will require the user to rejoin the projects and all unsent changes will be lost. Try to leave all joined projects before attempting to delete their Local Data.

More than one user is affected in the error

Probably the project database is corrupted on BIMcloud / BIMcloud Basic. If you have a scheduled snapshot, restore the project by using Rollback BIMProject or Library Snapshots. If you still experience the above issue, please contact your GRAPHISOFT support representative. For the investigation Archicad FastLogger files and BIMcloud log files might be necessary.
