Witness server issue in DAG

I am running into an issue which is don’t know what to do. Here is my situation. I have 4 member. Two DAG + witness server is on one network and 2 dag server in another network.

About 2 months ago I moved the Witness server to a new server:
Old server: ‘mmwitness’
New Witness:  “License”

Using the command line I setup the Witness server:
Set-DatabaseAvailabilityGroup dag -WitnessServer licensesrv -WitnessDirectory c:\dag

I also made Exchange Trusted Subsystem member of local admin group.

Today we had a network issue and databases moved from one network to another, it really should not have. The reason it should not have moved because the 2 dag members plus witness resides on the same network. When I looked at the Failover cluster log I saw a surprising error. It said:

File share witness resource ‘File Share Witness (\\mmwitness.xxxxx.com\dag.xxxxxcom)’ failed to arbitrate for the file share ‘\\licensesrv.xxxxxx.com\dag.xxxxx.com’. Please ensure that file share ‘\\licensesrv.xxxxx.com\dag.xxxxx.com’ exists and is accessible by the cluster.

I do not understand why there is something in my dag setup that still pointing to my old which is mmwitness server.   Why did I get this error?  

Can you assist?

Have the servers been rebooted since you changed the FSW?
If you run

get-databaseavailabilitygroup -Status | select identity, WitnessServer, WitnessDirectory, WitnessShareInUse

Do you get back what you would expect? Do it from all members of the DAG so you can be sure they are all returning the same.
