Using TCGAbiolinksGUI behind proxy server

[moko-3]

R closes the web browser's tab just after the TCGAbiolinksGUI is started. Error messages are as follows.

ERROR: [on_request_read] connection reset by peer warning: Error in curl::curl_fetch_memory: Timeout was reached: Connection timed out after 10016 milliseconds warning: Error in curl::curl_download: Timeout was reached: Connection timed out after 10000 milliseconds

How can I avoid the problems? I uses MS windows

I already used 'setconfig()' command as below. https://stackoverflow.com/questions/39285570/error-in-curlcurl-fetch-memoryurl-handle-handle-couldnt-connect-to-ser
