Hello,
we have the problem that we deleted the MSSQL ldf-files of Jira. We were able to create new ldf-files but Jira cannot still not connect to the database (error message in the screenshot)

I already checked the dbconfig.xml and there are still the right settings. I am also able to login to the database directly with the user and our firewall has also rules to allow the ports for the connection.
In the atlassian-log file i get the same error as in the Web UI

What setting am I missing? I don't get why I get this error.
