Endpoints required for correct operation of Sketch
Under certain circumstances, Sketch might not be able to communicate correctly with the server, preventing the application from receiving particularly important information. If this happens you will not be able to register or update your application, upload files to Sketch Cloud, or make use of real-time collaboration, for example.
The most likely scenario for this to occur is when working within a Corporate Network (via VPN, proxy, firewall, etc.).
Since these are very restrictive networks, we should check if all traffic to the endpoints shown below is enabled on your side. Traffic must be allowed in both directions (inbound and outbound):
capacitor.prod.sketch.com/ - Real-time Collaboration
graphql.sketch.cloud - Backend
client.sketch.cloud - Backend
auth.sketch.cloud - Authentication
resources-live.sketch.cloud - Download of Assets
sketch-resources-incoming-live.s3-accelerate.amazonaws.com - Upload of Assets
s3.amazonaws.com - Upload of Assets
api.prod.sketch.com - Licensing
download.sketch.com - Updates
download.sketchapp.com - Updates
If you do not know how to add these URLs to your whitelist, please liaise with the IT specialist in your organisation to perform these changes.
