Blender Installation Issues

Help

Hi, I am trying to use the Blender Connector, but get this error code when I try and press ‘load users projects’:

Any help would be appreciated.

Hey @Tom.Sargent,

Seems like there is an issue connecting to the server. It could happen due to an expired token or trying to reach a deprecated server.

So here is the debugging steps:

  1. Open Speckle Blender Connector and click refresh button.

  1. Open Blender’s scripting window.

  1. Copy and paste the following code snippet and run the script.
import bpy_speckle
import bpy
from bpy_speckle.clients import speckle_clients


client = speckle_clients[int(bpy.context.scene.speckle.active_user)]

streams = client.stream.list(stream_limit=10)

print(streams)

You should see the output in the integrated console. If not it should be in System Console.

In my case, this code is printing my streams. It could return an exception in your case, could you please send the output to us? So we can spot the problem :slight_smile:

Hi, thanks for the above. I have run through these steps and this was what appeared in the console:

Thought as well it may be worth mentioning this is in Blender 4.2.3

The unable to get local issuer certificate issue indicates that, certificate presented by app.speckle.sytems is not a trusted certificate which means there could be a proxy server in your network. Are you using any kind of cluster, VPN or maybe you’re within a corporate network?

Trying it from a different network could verify it.

I am logged on through a corporate network/VPN so it must be getting blocked here. I can get in touch with the IT team to see if they can unblock it.

Thanks for your help, and i’ll get back to you once i’ve got in touch with IT!
