Strange case : after one year of operation on current server webmail interface stopped working correctly. All settings in roundcube interface are working, but from ispconfig3 plugins works only one : ISPCONFIG3_PASS With all others (account, autoreply, fetchmail, filter, spam) it hangs for exactly one minute, then throwing error "Soap Error: Could not connect to host", but then it shows settings anyway. But of course no setting can be changed (if I change "autoreply" using ispconfig interface everything works fine.) Setting in /usr/share/roundcube/plugins/ispconfig3_account/config/config.inc.php are 100% correct and I am out of ideas what to check... I don't think this is connected, but have to mention anyway : I had to change ispconfig admin password + MySQL root password about two weeks ago. No other passsword was changed. Checked also remote user "roundcube" password in database, everything correct. No errors or warnings in apache or roundcube log files. Any idea where to look ?
