Fail to connect/access with Blender Speckle

I tried connecting with Speckle for Blender but always failed to access.
The add-on shows up in Blender settings, but I always get an error message when I try to activate it.

Traceback (most recent call last):
File “C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\modules\”, line 364, in enable
mod = importlib.import_module(module_name)

Exception: Failed to install dependenices through pip, got 1 return code

I only have this problem at our office workplace and contacted our IT specialists.

They told me that they generated the exceptions on the firewall as described in the FAQs, but unfortunately these weren’t the only ones.

I hope you can help. Thx

Hi, When you first launch the blender plugin, we fetch several python packages (via pip)

Looking at this stackoverflow post, it could be that your company blocks some of these domains.

Please could you try disabling any VPN software you have, and restarting blender.
If its possible to try a different network also (mobile hotspot?).

Once the dependencies are fetched, they shouldn’t need to be re-fetched until next you update the connector.

Please let me know if any of the above resolves the issue.

Thank you Jedd, for your help and quick response. I have now forwarded this to our IT specialists and am curious to see if they can fix it.

I will let you know if this was the solution
