Speckle not working after instalation

Hi!

The installation of Speckle went without a problem. On rhino 5 and 6.

Unfortunately I am not able to use Speckle. When I add the Data receiver or Data sender component in Grasshopper and try to log in I see this error:

The Speckle login screen is not closed. When I try to log in again Rhino crashes.

I tried reinstalling Speckle but I encounter the same problem.

Does anyone has a suggestion on what to do?

Cheers,
Bob

@Bob Which server are you using? It should be https://hestia.speckle.works/api/v1.
