The most probably Web Viewer can't reach Open Cloud Server. You need to perform the next steps:

1. *Change Web Viewer configuration:* [*https://cloud.opendesign.com/docs/index.html#/webviewer?id=build*](https://cloud.opendesign.com/docs/index.html#/webviewer?id=build)*. Parameter api\_host should point to the IP address of the Open Cloud Server.*
2. *Run Open Cloud Server with urls " dotnet OpenCloudServer.dll --urls http://0.0.0.0:8080"*
