Proxy Server - Spine User Guide
Support: Why can%27t Spine contact the update server%3F
Please make sure you don't have any firewall or virus protection software blocking Spine from connecting to the server.
The server is definitely up if you can reach esotericsoftware.com in a browser. This site may also be useful to verify the server is up. If it is, the problem is very likely to be with your computer or network configuration.
If you are behind a proxy, Spine can be configured to use your proxy server.
The servers are located in Japan and Europe. If you are located in China or your internet connection to the servers is very slow, you may just need to try multiple times or try again later.
