Hi,

check these things...

1. Windows failover cluster and make sure both DAG servers are member of
2. Make sure your witness server is up and running fine
3. Make sure all the Exchange related and Cluster services are running on both DAG servers

First check the connectivity between servers.

If connectivity is fine.
Please sure replication services are started
Please make sure cluster service is started.

Check the logs as well in the server

Please try below since you have left with single node DAG, I suspect it is quoram error
 Run the following commands with the EMS on mailbox server
 
 Stop-Service ClusSvc
 net start clussvc /forcequorum
 start-databaseavailibilitygroup -identity DAG
 get-databaseavailabilitygroup -identity DAG -status | fl name,primaryActiveManager
 mount-database DB1 -force

replace DAG name and DB1 name as appropriate
