Hail to all Professionals,

I'm facing a disconnection on a Microsoft SQL Instance with the below environment restraints:
I have a 2 clustered Database windows nodes hosting several SQL instances
Recently I failed over all instance to the second node in the cluster which now acts as active
Each time I conduct a restart on the passive node for maintenance purposes, one of my SQL instance suffers a disconnection during  the restart phase even though the passive node hold no instance, no mount point and no quorum partition only the guest file system, the others instance in the active node are not affected 
Teaming is configured between the 2 clustered nodes, drivers and firmware were checked and the application setup shows a connection with a virtual instance name with no configuration related to the physical passive server
