Hi, Have you installed the latest UR? Do you see any events related in the Operations Manager event log of the computer you are wanting to place into maintenance mode?

Hi @Rudragouda Masaraddi To resolve the error message "client has been disconnected" when trying to schedule maintenance mode for a group of servers in SCOM 2016, first check your network connectivity, firewall settings, and the health of the management server. If there are no issues found, ensure that the name and timing settings of the maintenance mode schedule are correct, that the servers you want to put into maintenance mode are included in the schedule, and that there are no conflicts with other schedules. Following these steps should allow you to successfully schedule maintenance mode for your servers in SCOM 2016. If you continue to experience problems, don't hesitate to reach out for further assistance.
Hi Rudragouda Masaraddi, In addition to what Deborah wrote, please check also did this blog entry by Kevin Holman: Enabling Scheduled Maintenance in SCOM 2016
As per Kevin:
This is caused by the SCOM Data Access account needing some additional permissions in SQL in order to control maintenance schedules via SQL Agent. You will need to configure this just once to get it going.
Please check the solution in the article. There could be also another reason for this, which is depicted here: How to suspend monitoring temporarily by using maintenance mode and here: Creating a maintenance schedule with more than 216 objects causes the Operations Manager console to disconnect
While creating or editing a maintenance schedule, you can't include more than 216 Objects at a time. If the number of objects exceeds 216, the following error message appears: The client has been disconnected from the server. Please call ManagementGroup.Reconnect() to reestablish the connection.
