The problem is the communication between Virtual Appliance and Database.

After that we have a SQL connection problem:

(pool-16-thread-1) IJ000604: Throwable while attempting to get a new connection: null: javax.resource.ResourceException: Could not create connection
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host <Host_IP>, port <Database_Port> has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
The problem is related to a communication problem between Virtual Appliance and Database
Virtual Appliance 14.2
Check if the connection with Database is working fine.
If some problem was identified, from the Virtual Appliance Dashboard redeploy the Database configuration to update its connection.
