I have an issue where ispconfig 3 control panel loads for a long time then finally works. I can see most the options and even log in but its just theres a white box with a loading animation and some links don't work until it's done. My best guess is it's trying to check for updates or reach other external URLs but can't because it's behind a proxy. How do I configure ISPConfig 3 to use a proxy when checking for updates etc. Like I did for YUM and the other applications. I'm using it as an internal webserver for some tools.
No it don't search for updates. May be proxy may be slowing the loading . To override it bypass the ISPConfig server IP in proxy settings.
I don't think that's the case. The default php website I have set up loads up no problem and is super snappy, it's just ispconfig control panel that is taking forever to clear the white box.
