github connection reset

Hello! Has anyone ever had problems with github reseting/refusing the conection? I can deploy on test server but not on live. Coonnection with server is ok. This is the error: Resolving api.github.com (api.github.com)... 140.82.121.6

Connecting to api.github.com (api.github.com)|140.82.121.6|:443... connected.

HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.

Retrying.

Thanks
