Unable to Send Model from Grasshopper to Speckle Stream

I am unable to send a model from Grasshopper. The error I am getting is shown in the picture.

Hi @Qam,

Welcome to Speckle!

Are you by any chance using a firewall? Or do you have any IT restrictions from your company in place?

Here are some important URLs Speckle needs access to: FAQs | Speckle Docs

Can you please try using a different network and see if that works?

Let us know how it goes.
