Hi @Alexi_Andriotti,
Thanks for writing in to ask us about this issue. The error message that you showed in your post tells us that automatic port forwarding was unsuccessful. You have two options from here. You can either set up the port forwarding manually or use Tailscale instead. I would advise using Tailscale as most of our users find it to be a simpler process.
You can try the Tailscale method by following this article.
If you prefer to use manual port forwarding follow this article.
Please let us know if you have any further issues.
