I applied for Multi-Cloud Connect from the business portal but it is displayed as out of service hours.
On-demand application acceptance is "Weekdays from 9: 30 - 17: 30 (Saturdays, Sundays, holidays, New Year's holidays excluded) in JST".
If you have any questions, please contact the office of Arcstar Universal One.

Can I subscribe "VPN Connectivity" menu via portal?
