Hi Guys, I am seeing this error in the log every so often. Running ver 5.01: Tue Nov 3 10:20:26 2015 error OTRS-otrs.Console.pl-Maint::OTRSBusiness::AvailabilityCheck-10 Can't perform POST on https://cloud.otrs.com/otrs/public.pl: 500 read timeout Tue Nov 3 10:20:26 2015 error OTRS-otrs.Console.pl-Maint::OTRSBusiness::AvailabilityCheck-10 There was an error executing Execute() in Kernel::System::Console::Command::Maint::OTRSBusiness::AvailabilityCheck: ERROR: OTRS- otrs.Console.pl-Maint::OTRSBusiness::AvailabilityCheck-10 Perl: 5.20.2 OS: linux Time: Tue Nov 3 10:20:26 2015 What exactly is the software trying to "POST" to https://cloud.otrs.com/otrs/public.pl? Should I concerned about these entries in the log? Also, since upgrading to OTRS ver 5.x, when closing a ticket, a subject field for the close note has now appeared and is mandatory? Is there any way to revert this to the previous behavior where just a note entry is enough? Cheers, A.
