Don't know what the hell is going on: Server is down: I was checking settings for Websites at that moment in ISPConfig 3 22.214.171.124 and was losing the connection to the server. I restarted the Server using Ctrl + Alt + Del, still the same. Could use PuTTY and WinSCP while later was getting very slow. Ping to the server also works well. Mail Server still seems to work, have to wait a bit to see I could receive mails. Access to ISPConfig is denied from either local LAN or external 3G! Anybody has any idea? Thanks. Edit: Mail works, just received new mail. Send works as well. It's ISPC only which didn't start. How to reset ISPC? Thanks.
