Symptom: Looking at the v2u service logs (BackOffice: C:\Venue2U\Logs) SendOrder Response is taking more than 15 seconds.
Things to check:
Configured till ip address is ok.
Till table tracking database setup in BackOffice under Locations.
Restart of all back office services (pc restart) required before this takes effect.
