Access marketplace have connection error

Hi All.

I was installed PIWIK on my local server . It is runing well now.
But when I access platform ----marketplace ,there is connection error
" curl_exec: Failed to connect to plugins.piwik.org port 443: Timed out. Hostname requested was: plugins.piwik.org" .

Can any friend suggest how to fix this problem?

My piwik version is 3.04.

Thanks in advance .

Hi,

the error messages means that your server can’t connect to plugins.piwik.org.

Can you check if you are able to connect to it (e.g ping/curl/wget/dig)?

Thank you vech Lukas.

This is issue was fixed .
I was add proxy server and port to config.ini.php . Then issue has been fixed.
