Queue Database is not accessible due to the Machine translation Service Error –

We can see the error in Machine translation service saying that "Queue database is not accessible." By checking into deep we can find the summary text as "Machine translation service cannot access the content that it has to translate" We can see this error whenever new machine translation service jobs are not complete or existing items are going to be hanged".

We can get this whenever queue database is not able accessible or not having valid permissions to access custom database. So that we have to check for SQL Server Machine database or verifying the SQL Server network connection.

To verify the SQL Server Machine translation service DB,

Find out the Machine Translation Service DB server and Name and version of Configuration Database. Check SQL Server for configuration database if it is not exists, run SharePoint configuration wizard.

To Verify the SQL Server network connection,

Navigate to Farm Information page in Central Administration (System Settings -> Manage Servers in this farm). Check for the Database server. Open command prompt and ping the server name to confirm server is working or not. If we get failure message, there is some problem with network connection that prevents responding. We can fix that issue by logging in to the server.
